Low-profile AC unit replaces the Dometic air conditioner on your RV or camper. AC plugs directly into your Dometic setup to work with your existing air distribution box. Start capacitor jumpstarts AC when camp or generator power isn't enough.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.
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!!
Great customer service and communication a slight delay on the shipping due availability of the specific A/C ordered.
Arrived early, had some damage on the case but works as should and plugged right in to my Dometic setup. I’m glad I used etrailer and will again if needed
The delivery was extremely timely and everything that was promised was kept! I know I will be calling again, as RV's always want some attention.
Thank you!!
excellent product with excellent customer service. Amy J. worked quickly to resolve some shipping damage issues and cross ship replacements.
Fantastic and easy to work with. Thank you
Quick, great price and arrived exactly when they said it would.
You do what you say for good consumer r eport
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.
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.
Do you have a question about this RV Air Conditioner?
