Hi, Don with Etrailer. Whether you're replacing a rooftop air conditioning unit on your trailer or if you're adding a new one, this is gonna be a good option for you, this is the new Low Profile series from Advent Air, this is gonna come with a white shell or a black shell. This is gonna come in two different power requirements with, depending on your camper size, and the output that it can handle, this is either gonna be a 13,500 BTU, or today's installation, a 15,000 BTU. Now in this particular camper, we replaced a much larger air conditioning unit with this smaller one, that's gonna be a smaller footprint, this is good for anybody that's looking to make a little bit more room up on top of the camper, whether it be for solar panels or optional other equipment that you wanna put on there. We did a size comparison between this newer Low Profile unit and the unit we took off, let's go check that out right now. Now just real quick, we wanted to show you the size comparison between the unit that we replaced in this Evertail unit over here, and then the new Advent Low Profile series here.
And it's not always about the size, this unit over here is a 13,500 BTU unit, while this Advent here is a 15,000 BTU unit, it's just, the dimensions are gonna be a little bit smaller for ya, and this is something to consider, if you have limited space, up on top of your trailer or camper, if it's loaded up with either skylights or vents, or TV antennas, and if your space is limited, you definitely want to check that. For instance, the height on our Low Profile unit, we're gonna be running about 11 inches above your rooftop, whereas on this unit here, we we inchesre about 14 inches. So you're saving around three inches just in height alone. As far as width, the Advent unit's gonna come in just around 25 inches or so. And on the Evertail unit that we're replacing, it's about 30 inches.
The other measurement I like to get is gonna be, from the intake, and exhaust, right here, on the bottom. It stops right here. And this is usually where people run into problems, on top of their camper. Because they'll have a TV antenna or something that's set up behind it, and it's gonna interfere with it, on our Advent today, that's only 11 inches. Whereas, on the Evertail unit, we're running about 13.5 inches with that, so, this is really an option to consider if you have limited space up on top.
So that really was a dramatic difference in size between the two. If your camper can handle the power consumption, I would recommend going with as large a unit as you can take. This particular model, if you go with the 15,000 BTU, it's gonna draw 15.4 amps while it's running. So just keep that in mind and check your camper's power requirements, make sure that you can handle that much. Let's go take a look at the inside, and check out some of the controls.
With this setup, you're going to get a thermostat here that's gonna power the unit, it's gonna be cool mode, a heat mode, and then a fan-only mode, and it's gonna have three speeds on the fan, high, medium, and low. So to cycle through, you can just hit the Mode button. And it's gonna control not only the rooftop air conditioner, but it'll control your furnace if you have one as well. If you just want fan mode, you can kick it to fan only, and then adjust the speeds to medium or low. As far as the air box down here, you're gonna have separate air duct controls, you can open these or close them, on this particular camper, we have a duct system, so, we have the option of having some air exit through here or go through the duct system, so this'll work for ducted or ductless systems. It has a washable, replaceable air filter element right here. If you can just pull that out, wash it, replace it back up. All in all, I think this is a great little setup here if you're replacing, or even if you're just gonna add air conditioning to your camper, Advent Air, they seem to be fairly easy to install, whether you have a Furrion system or a Coleman system or a carrier setup, we have different adapters available to make this unit plug and play. Especially if you're replacing the unit, you already have thermostat wiring run. This really is a fairly straightforward installation, if you wanna see how we installed our unit, and the thermostat on this particular camper, stick around. So to begin our installation, we're gonna start on the inside of the camper, if you're doing this as well, and more than likely, you're gonna be replacing an existing unit. It's gonna be similar to this, but depending on the manufacturer types, it's gonna be just a little bit different when doing this, but the first thing we're gonna do is get this cover removed. On this one it looks like I have four Phillips head screws. We'll get these outta here. So with that cover removed, it looks like we have four 10-millimeter bolts that are gonna actually be holding our air distribution box up here. Now more than likely, your electrical connections are gonna remain hooked up, of course, you wanna make sure that you have any AC voltage turned off. You're gonna have both 120 volts up here and 12-volt wiring up here. Need to get the lower plate disconnected from the upper unit here. We can start, this is gonna be the free sensor, now our new unit is gonna come with a new free sensor. So we can disconnect this, that'll go up with the old unit. We can disconnect the box, now the good news is, and this is what you wanna look at when you're replacing, you wanna see that your plugs are gonna fit up with the new box, and in our case, it's going to, we have different adapters for different boxes and manufacturers, so, you definitely want to check that before you make a purchase. Other than that, the rest of this is going to be thermostat wiring, we're gonna disconnect. And then our 12-volt wiring is gonna be right here. And then our 120-volt wiring is gonna be right here, and we're gonna have to open this box up and disconnect it from the inside. Okay. Now with everything disconnected, there's nothing right now that's holding the top unit on, when we took the four bolts out, that was actually what's holding this unit on. So we're gonna head up to the roof on this camper and remove this unit, and replace it with the Advent. I'm just gonna lift at the corners. It's gonna be a foam rubber seal, that goes that goes around, but, it might be sticking to your roof a little bit. But. Okay, gonna tilt this up. You're still gonna have your wires, like the free sensor wire. And then your control wires are still gonna be on. And you wanna be careful sliding the old unit and new unit around up here on your roof. Now anytime you're up on your roof and you're replacing an AC unit, it's a good idea to inspect your roof, and clean it up a little bit too, and that's what we're gonna be doing here today, make sure we don't have any dry spots, or dirt, and we're gonna clean up the mating surfaces here. Make sure we get a good watertight seal. So when you're placing this unit, you just wanna make sure you get it somewhat close to lined up on the hole here, you're gonna be able to reach up from the bottom, and adjust this however you need it. So, that's gonna work for us. And we can head back inside and tighten it down. If you need to move this around one way or the other, you can just square it up, make sure your seal it is even all the way around. And before we continue on with the installation, we can reach up on the inside and we're gonna pull down the power distribution cable that's up here. And now it's also a good time to install the free sensor. Now that's gonna come with your kit right here. We're gonna undo this. And the copper-colored end actually goes up into the evaporator up here, you're gonna see a blue plastic piece, that this slides right into. And that is one of the things I like that Advent does, it kinda makes it easy. Some of the other manufacturers out there, you have to get a screwdriver and sometimes move the fins side to side just to get the free sensor up there. So we have this installed. And, next thing we can do is install a control box. Now you'll wanna have your bolt kit handy. Just gonna run this straight up, now all of your wiring needs to go on the one side here, where the wiring. Goes. You don't want anything caught on the other side, this is the intake side. This is where the air is gonna get drawn up into the air conditioning system and the exhaust side over here, the cold air, comes down over here. So we're gonna be having a wall, a divider here, to keep these two areas separate. So we want to make sure everything is on this side, and it is right now. And we can just take our bolt, and we're gonna run them up, into the unit. And if you're lined up correctly, they should just start. I like to run the bolts up and make sure everything is centered, and then just snug 'em up. And we're just snugging these up right now. And once I make contact at all four corners, we'll make sure that this gets tightened up equally at all four corners here. Now as far as tightening down the upper unit to the lower plate down here, there are torque specifications in your instruction manual that tell you a torque value on these bolts, but I would also say that, you know, you obviously want this gasket up here to compress as much as possible, but, without deforming your ceiling, so, just kinda use your own judgment when tightening this up, we don't want the upper unit to move, we definitely don't want it to leak. But each ceiling's gonna be a little bit different. So to begin the wiring, we'll start with, obviously, the easiest ones, that's gonna be the plug from the upper unit. It's just gonna get plugged right in, these will have a flat edge on the top and bottom and in the middle, over here. And that'll let you know the orientation, this is only gonna be able to get plugged in one way. And then, our free sensor, that we stuck in, to the top, is gonna have a pigtail down here. And that's gonna hook up, just like the other one. And then from here, this is where it could be a little bit different for you. We're gonna hook up our thermostat wiring, our furnace, and our 12-volt wiring here. And then our AC voltage, so I'm gonna get all this wired up right now and we'll kinda overview it, in just a second. Something I do want to share with you, that took a little bit of troubleshooting on this, and you may run into this issue, on our old control box here, we had two wires for our furnace, we had a furnace positive, and a furnace negative, and on this Advent Air, there's only one wire, and it's gonna be just the way the disk box now controls your furnace. So on this one wire here, we hook this up to our furnace negative, and what that's gonna do is supply the power to our furnace, and we capped off the positive. On the other box, of course, we had the positive and the negative. But this is the way that it needs to be wired on this system, so again, this is the furnace control wire, that's hooked to your furnace negative, and this is gonna kick your furnace on and off, from the control box here. And then we just capped off, if you have a furnace positive wire like that, just cap that off. We have everything wired up, I've got my AC voltage wired here with the wire nuts. And I'll end up tucking that inside the box. And then the rest of this stuff, the thermostat wiring has been hooked up, and the 12-volt wiring has been hooked up, I'm just leaving it hanging loose for right now, because we need to do some work up inside the box. Namely, we're going to be installing this divider pan, so we can take off the styrofoam that came with it. Now, on most roofs, this thing's just gonna go up with no problems, if you have a thinner roof, insulation wise, this can be broken and cut along this line here for a thinner application, for us it's gonna work just fine. What you'll see on the inside of this unit is a white tape strip, along this back side. We need to take this off. This pan is gonna get installed up, and it's gonna stick to this, but, we wanna compress this gasket up against the bottom part of our upper unit there. What we're doing is we're just making sure air on this side stays on this side, and air over here on the other side stays over there, so, we're gonna put the divider up, and what I like to do, is kinda compress the gasket, make sure we're all the way up against the top of that unit up there. I like to use foil tape, this is not included in your kit, and this is like metal duct tape, and this foil tape, I'm gonna run this around the top edge up here, and also right here, and seal this up, before we put up this foam insulation, now this came with our kit. And what this is, this is gonna also be sticky foam. And we're gonna be applying this against the divider piece that we just put up here, what this does is it acts as a thermal barrier against the other side, and it'll just keep condensation from forming, and dripping down into your RV here. This is gonna be cut to fit, and you're gonna wanna cut this to fit this whole section here, and then stick it directly to it. So this was the end result over here, it's not the prettiest, I'll admit it, but, we've got the foam that's insulating the divider, and I just use foil tape wherever else I saw a hole in there, this particular system is gonna be using the duct work on either side, so, this is going to be all sealed down here, so any leaks that we woulda had going over here, or through the partition, is gonna be less air moving through our vent, so that's why I'm pretty particular about making sure that this stays insulated and sealed against the other side. Now over here on our wall, because we we inchesre replacing a unit with a thermostat, we already had the thermostat wires run. This particular thermostat is gonna use four wires, and that's pretty common. And the four colors they're gonna be using is blue, yellow, red, and green. Now you'll have a little diagram up here on the back, telling you which wire goes where, this is gonna be the 12-volt positive, the common or negative, and then your furnace A and furnace B wires. Now I've got all the connections on the back of our thermostat here. That's gonna complete all of the connections for our installation, now, I've went ahead and turned on the 12-volt power and the AC power. And what I like to do is just turn everything on before tucking this away and making sure everything's gonna work properly, so, I've got the fan on right now, and we're gonna turn it on. (fan blows) And that's gonna be blowing fan air straight out right now, on the bottom side, this is what we want. And we can check, we'll put it on cool and have the compressor kick on. So our compressor is kicked on. We're gonna let it run for a little bit, make sure it cools down. And if that's the case, everything's working normally. I'm gonna probably take some zip ties and get these wires tucked away, get the protective shield over our AC voltage here, and then we can install the lower plenum. You need to remove the filter And that'll expose four more of the screw holes here. Your kit's gonna come with screws and cover plates for these outer holes here. Just install these. I like to start in the middle and then end up at the four corners here. With all the screws tight, you can install the blanking plugs here. Looks like they are oriented, to where this little tab'll be towards the inside corner here. And then we can reinstall the filter, this filter is washable and removable. And that was a look at some of the features, and the installation of the Advent Air Low Profile rooftop air conditioner.

Low-profile AC unit for ducted or ductless system lets you replace or add a new AC to your RV. Wall thermostat has an LED display and controls the mode, fan, and temperature settings. Air distribution box has 3 slotted registers for maximum airflow.Delivery was quick - two days. The AC arrived undamaged. E trailer has plenty of great installation videos which made the process smooth and uneventful. Everything performs as promised. For some reason Advent air conditioners don't come with a hard start capacitor included and they were on back order virtually everywhere online. So the 2 week plus wait for that was a bit annoying, but by no means a game changer. Basically Advent us a great unit at a great price that was easy to install diy.
Fast shipping. Thank you.
So EASY it aughta’ be CHEESY!!! Unboxed AC Unit, noticed two dents in the unit but none of the parts looked damaged or inconsistent; So I decided not to call regarding minor damage, instead I decided to install it by using two ramps I made out of scrap wood. TIP: the wooden ramps made it so simple to install the unit with minimal effort and two people. This made it a breeze to put in and I really recommend using this tip when installing your unit… The New Advent AC Unit made is so simple to plug into the dometic. This unit is made for easy installation and almost a universal fit. Great Experience at this establishment and happy with their product and selection of RV and Trailer parts. I will definitely recommend to all my fellow RV’ers! Happy Shopping! Always remember… Keep your library card updated!??????
I purchased this 15,000 BTU unit with the direction from customer service. I was told that it was a replacement for my original Dometic AC on my 5th wheel and that it would mount and have identical wiring.
They were very helpful and correct. It was extremely easy to replace. The mounting bolts and wiring hook up were identical to my old unit. The hardest part was getting it on the roof of my camper which actually wasn’t that difficult. I put an old piece of carpet (upside down) on the roof to protect it. I used my tractor with a front loader to lift it as high as I could then just set it up on the roof.
Once I removed the diverter/trim from the inside ceiling there are 4 bolts holding the unit in place, one wiring plug and the freeze sensor attached to the evaporator. Once that was all done it just lifted off the roof. After cleaning the roof where the old unit set, I simply set the new unit on the same seal footprint. I went inside hook up the wire plug, located the freeze sensor and tightened the 4 bolts. Don’t tighten the bolts too tight, just enough to hold it tight and adequately compress the foam seal.
The overall size of the new unit is shorter and smaller than the Dometic.
Ordered a different unit, noticed the next morning that shipping had changed and unit was not gong to ship for another two months! I called the help line, the gentleman I spoke with was very helpful and found me this unit that would work and was in stock. Unit arrived a few days later, however the side was dented and the cover is broken. It is summer and we have camping plans this weekend so I installed unit anyhow, everything is working as designed, it cools my RV nicely and is much quieter than the original unit. Cover is still cracked, hoping to find who to call/email about getting a replacement shipped to me?
Dropped the old Dometic off my roof while doing a repair. I’m now glad this happened because it forced a great upgrade. This unit matched right up to my Dometic Airbox perfectly. The low profile unit is much smaller than the Dometic, without sacrificing any performance.
Item arrived damaged by UPS. I contacted etrailer & they are sending a replacement. Very good customer service. As you can looks like the unit was thrown around during shipping.
Installed unit with Coleman adapter harness and A/C compressor comes in, condenser starts cooling, but fan never comes on. I voiced my concern that i think the blower motor is bad, but after contacting eTrailer, I was instructed that I'd need to spend more money and purchase Advents, compatible over head control box. Installed everything recommended and guess what??? Still no fan operation. Pulled the upper cover off the unit, checked for voltage at blower motor on all speeds and yep, you guessed it, voltage at the blower motor. I spent so much money to replace a Coleman unit that was working, just struggled in the heat of the day. Overall, the whole experience has been garbage.
The first part of this review is for etrailer. Fantastic customer service as usual. The unit was back ordered when i placed my order and they kept me updated the whole time, and it actually arrived earlier than expected. Unfortunately I received the unit with a fan blade that was damaged during shipping. They sent me another unit immediately to resolve the issue. More companies need to be like etrailer.
As for the unit itself; I’m very impressed. I installed this on my high roof sprinter to replace the existing 12 volt unit since I needed something stronger. Install couldn’t be easier. It’s not terribly heavy, I carried it up the ladder by myself.
The soft start makes it possible to run off my 12v battery bank and 4000watt inverter with no issues. The 12v unit i replaced would take about an hour to get the whole van down to temperature, the advent unit takes maybe 5 minutes to cool the whole van off.
An absolute game changer for me. Very quiet inside, outside is a bit louder than the 12v unit but quieter than many 115v rv units I’ve seen.
Direct replacement for a 10 yr old Dometic. Four bolts and plug in one connector and the camper was cooling. No adaptors needed. I wasn’t sure of the quality or ability of the unit as it was less than half the price of the replacement Dometic, but so far I’m impressed. I set the T-stat to 68 and within an hour it got to set point during these 90+ degree days. I read a lot of reviews of these units being damaged and this one followed suit. It has a dent in the metal frame just as others have observed, but it didn’t affect the mounting of the unit or cover. There was no damage to the shipping box or packing foam. My guess it’s was a production issue. Time will tell on how long it last, but with proper filter maintenance and coil cleaning it should give many years of good service. It does include an 2 year limited warranty, just remember to fill out the paperwork for it to be valid. Only negative, it is made in China, but most things are these days.

In short, it was a simple drop in replacement for my Dometic Brisk II unit. The Dometic thermostat operates this unit without issue on low and high speeds. The toughest part was getting the old unit down and the new unit up on the roof. Hopefully this one will outlast the previous two Dometic units that both had major freon leaks within two years. Warranty did cover the cost for the replacement unit. I do like the low profile and smaller size of this unit It performs equally as well as the Dometic unit it replaced. The sales staff were helpful providing detailed information not to mention all the available specs, diagrams, videos, etc. on the website. This long time electronics tech has been impressed. These days that doesn't happen very often! 50
It literally took a half hour to install. I’m so happy that I did it myself and I would recommend it to anybody. Today is July 5 and it’s 106 outside here in AZ and I’m inside my trailer, nice and cool, excellent product.
AC works, however, the bottom half of the unit was bent, someone damaged (bent it) the bottom portion and must have put a new top cover on it and boxed the unit up. The box was in perfect shape.
Changed out dometic 13,500 BtU conditioner with 15,000 BTU with Advent Air. The fit was exactly the same dimensions with the same plug for thermostat and other controls. All I had to reconnect was the 115v electric. When started it took about 30 seconds for fan ramp up to full speed and then compressor kicked in. Two people took two hours. One person had previous experience. Should work well cooling a 30ft fifth wheel camper.
We are very happy with our Etrailer purchase! We replaced our 13.5K BTU Dometic Brisk 2 with a comparable low-profile Advent unit. As we were not totally sure of which unit to purchase, we made a quick call into the call center to confirm compatibility. The call center was very friendly & helpful. We received our A/C unit in a timely manner with only 1 minor dent from the shipping process. This did not appear to compromise the unit's function, so we proceeded with the install. As many customers have noted previously, the hardest part of the installation was getting the unit onto the roof. Installing the provided start capacitor went smoothly and the unit fit our Coachmen Apex's measurements well. The plugs & wiring were compatible making the final change-over very easy. As noted in the unit's description, installation hardware is not included in the purchase but was not necessary, as our existing hardware fit precisely. Our new unit is better-looking & much more aerodynamic and compact. Best of all it is MUCH quieter & seems to cool very efficiently in our humid, Southern heat!! Etrailer saved us hundreds of dollars with this purchase, and we can't be more satisfied. Thank you Etrailer! :)
I included a photo of my husband's method of getting the unit onto the roof for your enjoyment.
So far so good, I ordered two of these to replace my existing units.
One unit arrived damaged, but is working OK.
They seem a little noiser than the Coleman Machs.
Working good so far.
Upon what should have been a simple routine installation, three of the four mounting bolts which screw into chintzy riveted-on threads became difficult to screw in, which snapped the riveted thread from the unit, rendering it virtually uninstallable. Insult to injury was learning that e trailer does not stand behind this unit and punted to the manufacturer "warranty" which is a complicated process that involves removing the unit (need to cut the bolts on my case which would be very difficult without damaging the unit) and bringing the 100 lb air conditioner to an in-network dealer (while of course leaving your RV unusable with a hole in the roof) and waiting for them to fix it. Not sure who has time for that but it isn't me.
Bought this to replace an older (2007) Coleman 8000 on our pop-up. Had a bit of a time installing this. Please, READ THE INSTRUCTIONS and LOOK AT THE PICTURES. I had the upper duct that mounts to the roof unit installed 180 degrees off.
The converter kit that you buy with this if you're replacing a Coleman, didn't fit my Coleman panel. It's made for newer units. After talking to etrailer and the manufacturer I found I had to purchase a new control panel for inside. Another $85.
Overall it wasn't a bad job once I figured out the upper duct and the control panel issues. Unit cools well. About the same noise level as the old Coleman. It is not as thick top to bottom as the Coleman was. Think it's a little lighter after picking up both! Real test of how it works will be the trip we're taking next month.
have installed a few ac's over the years the smaller profile and weight as well as a simple plug and play made this advent a success in application . benefits over commercial dometic it replaced were quieter and less vibration as well as a general feeling of cooler throughout my 36 newmar .las vegas heat will continue to challenge the unit , we'll see if it survives the summer. so far pleased !
Etrailer came for the win. After trying to order from Amazon and having my order cancelled I went to etrailer. I got a better RV AC unit for $50 less and shipped the next day.
Etrailer now has all my RV business.
As I write this review i have not installed the AC unit and cain’t comment on it, but would like to say that I am extremely pleased with the service provided by etrailer. The unit was damaged in shipping and etrailer.com was very helpful in resolving the issue and getting the part replaced in a very timely manner. I will without a doubt continue to do business with them for any future purchase.
Ordered one you didn’t have in stock cancel the order called and talked to your salesman had to cancel the order was going to refund that order and charged me again i have not received the money yet I paid for two only got one
When it was delivered, I didn’t open box because our RV is two hrs away. We got there today and opened box and naturally there was a dent on top left side, it mashed the top down on one side and pushed fan cover on fan- so we had to straighten that out so fan could run with no noise.
Replacing an aged Carrier Air 5. This unit was plug 'n play with the old controls ... as I didn't want to give up the old remote or worry about the furnace interface. Will was great on the phone and got me all I needed, plus follow-up on shipments. The new unit is a bit louder, but the air is cold.
I thought that my existing control panel would work with this unit from what I read on etrailer when purchasing. So is not the case... Need to order a new control panel so I can get this thing working!!
