Your old AC gave up in the heat. You could fix it, again, or replace it for good. This kit makes it easy: the components are matched and you get the kind of cooling comfort that helped you fall in love with your rig in the first place.
One of the biggest headaches in RV repairs is figuring out which parts are compatible. This kit takes all that off your plate. The rooftop unit and air distribution box are made to work together, so installation is smoother and nothing catches you off guard. Whether you're doing the install yourself or paying someone else to do it, having everything designed as a set makes the job faster, cleaner, and less stressful.
If you've ever had an AC that ran all day and still left the rig feeling muggy, this one's a different story. It's made for RVs without ducted air, so it's perfect if you're replacing an old setup or adding a second unit to cool a separate space. And with 13,500 Btu of cooling power, you'll feel the temperature shift within minutes, not hours. Inside the unit, large coils and airflow-boosting fins help pull heat out efficiently, so your RV stays cooler with less strain on the system. You walk in, and the air feels dry, cool, and breathable—like a good night's sleep is actually possible again.
The air distribution box gives you full control right at ceiling level, with simple knobs you can reach without digging for remotes or climbing over furniture. You can direct airflow where you need it with adjustable dampers, and when the filters need cleaning, the pop-out grilles make it easy. No tools required. Just pull, rinse, and snap it back into place.
Sometimes, it's not cold enough to run the furnace, but it's too chilly to be comfortable. This system is prepped for a 5,600 Btu heat strip (sold separately), which is a simple way to take the edge off on those in-between mornings. It's easy to install and helps your space warm up without the noise or power draw of a full furnace cycle.

Hi everybody. Andy here with etrailer.com. Let's take a look together at this Coleman Mach Signature Mach 3, 13,500 BTU ductless RV air conditioner system in this polished white shroud. Now, as you probably know, one of the biggest headaches in RV repairs is figuring out which parts are going to work together. This kit's gonna help take all of that off of your plate. This rooftop unit comes with an air distribution box that is designed to work together with this unit.
And so because of that, installation should be smoother and nothing should catch you off guard. So whether you're doing the install yourself or you're paying for someone to do it for you, having everything designed to work together in a kit like this is going to make your job go a lot faster, cleaner and be a whole lot less stressful for you. Now this system is made for RVs without ducted air, so this is gonna be perfect if you're replacing an old setup or you're adding the second unit to cool a separate space in your camper. At 13,500 BTU, this is going to give you enough cooling power, for your smaller to mid-size RVs, think like 30 feet long and shorter. And inside the unit are large coils and airflow boosting fins that are gonna help pull the heat out efficiently so your RV's gonna stay cooler with less strain on the system.
And taking a look at some measurements here of the unit itself, the overall length from end to end, it's roughly about 39 inches long. The overall width, again from end to end, is gonna be roughly 27 inches wide or so, and this is considered a medium profile air conditioning unit. So the overall height's gonna be almost 14 inches tall. Now this unit is built with copper tubing and secure joints, so that's gonna help it stay sealed and running season after season. And we do have this streamlined medium profile shroud that's gonna help reduce drag.
That polished white finish is gonna give you a sleek look, blending well with most modern RV aesthetics. I did want to point out that on the side and on the front is where we get that polished texture, that shiny texture, but it's on the top and the back, we have more of a textured matte finish. So it's kind of a two-tone finish. And if you notice, it's not hard and rigid like some other air conditioner covers are. There's a little bit of give to it.
So I think that's good in that it's gonna be more impact-resistant. I don't think you're gonna have to worry about it cracking or fracturing as easily upon impact like some of those harder ones. But all in all, I think it's gonna do a great job of protecting those internal components. Now the air distribution box here, which is included, is gonna give you full control right at ceiling level with simple knobs that you're gonna be able to reach without any issue. You're gonna be able to direct the airflow as well, the speed and the direction. So this is gonna be a really easy unit to use. And another nice thing about it, it's gonna be very easy to pop those air filters out, wash them out, rinse them out, let them dry, and then you can replace them. It's so very easy to keep your air clean and that airflow going at a very optimal level. Hardware is going to be included with this. So you're gonna get everything that you need to get this mounted into place. Giving you some measurements here. The overall width, we're about 20 and three quarters inches wide. The overall length, about 21 and three quarters inches long. And I just wanted to show you what this is gonna look like sticking down from your ceiling. So it's not gonna take up a whole lot of head space. This is probably gonna stick down about two, two and a half inches or so. And then just wanted to give you a view of the other side here. So this kit is, like I mentioned, all designed to work together. And this is not gonna be compatible with any air conditioner components or systems from 2024 or earlier due to the fact that this unit uses the new R32 refrigerant. So if you have any other components in your camper or RV air condition components from 2024 earlier, it's probably not gonna work with this system. All the components must work with that new R32 refrigerant. So that's why in regards to this kit, it's nice that you aren't gonna have to worry about that fact that everything is designed to work together. One other thing I wanted to mention is you could pick up a heat strip for this as a separate purchase. Now a heat strip is not designed as a furnace replacement, but it's just something to have additionally to take the edge off the air on some of those cooler mornings where you don't really need to fire up the furnace. So if that's something that you're interested in on your screen, I am including our item number. And again, that would be a separate purchase that you could add to your order, separate item that you could add to your order. It should be a pretty simple install. Now, if you happen to have any other additional questions, whether it's about this kit or any other air conditioner kits that we carry here at etrailer.com, don't hesitate to reach back out to us. We ultimately wanna make sure that you're getting exactly what you want and need. Well, that's gonna wrap up our look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
