Keep your RV comfortable after long drives, sunny afternoons, and warm-weather camping days. This 13,500 Btu unit connects to your existing Advent Air R32 system to deliver stronger, more consistent cooling throughout the cabin.
After a long drive or a full day parked in the sun, your RV can hold heat in the roof, walls, and furniture, well into the evening. This 13,500 Btu rooftop AC delivers 430 CFM of airflow to help bring cabin temperatures down and keep cooled air moving through your compatible Advent Air setup.
If the rooftop AC is the part that needs replacing, you may not need to change the entire interior setup. This unit replaces the outside air conditioner and connects to compatible Advent Air R32 air distribution boxes and controls. The 6-pin plug helps link the rooftop unit to your existing compatible system without rewiring the whole AC setup.
This replacement unit is made for compatible AC systems that use R32 refrigerant. That matters because older systems and newer R32 setups do not always use the same controls, wiring, or interior components. Before installing, confirm that your current air distribution box and controls are compatible with this R32 rooftop unit.
A rooftop AC replacement needs a good seal where the unit meets the roof. The thick, collapsible gasket helps block rain and hot outside air from entering around the opening, while six foam pads help cushion the unit and reduce vibration at the mounting point. That helps the AC sit securely while keeping the cabin drier and quieter.
Replacing a rooftop AC is easier when the unit is designed to connect to the system already in place. This AC uses a bolt-on installation and includes the wiring harness needed for compatible setups. The UV-resistant hard plastic cover protects the internal components and can be removed for maintenance and cleaning when the unit needs attention. If you'd like help installing your air conditioner, check out our Installer Locator to find an installer near you.
Some camping setups ask more from your AC than others, especially when you are running on generator or campsite power. The optional start capacitor (ACMSCKIT) can be added to help the compressor start more reliably. This upgrade is not included, but it gives you a way to build out the system for the way you camp.

Hi everybody. Andy here with etrailer. Let's take a quick look at this Advent Air White 13,500 BTU RV Air Conditioner. Now this 13,500 BTU RV AC is designed to cool down your camper or motor home quickly and efficiently. So this is gonna be a solid upgrade for you if, let's say, your current AC isn't keeping up or it's gonna be a great option if you're adding an AC for the first time. So again, this is gonna be made specifically for your RVs, your motor homes, your travel trailers, and 5th wheels.
But I do wanna let you know that this one has not been designed for things like school buses, food trucks, or utility trailers or off-road vehicles. Typically the roofs on those type of vehicles or trailers are not reinforced enough to handle a unit on top of those vehicles or trailers. So again, this is a 13,500 BTU unit. So this is gonna be ideal for let's say smaller RVs and in moderate climates. It's gonna handle normal conditions without overloading your system.
A 15,500 BTU unit that you can also get this in, those are gonna be better for your larger RVs in hotter climates or heavy sun exposure. It's going to cool faster and keep up in extreme heat. Before we go any further, let's go over some measurements. So the overall length here from end to end, I got roughly 32 inches long. The overall width here at the widest point, about 26 and 1/4 inches wide.
Then the height's gonna be roughly 13 and 1/2 inches tall. You're gonna be able to use this unit in either a ducted or ductless system. Of course, that's going to depend on the type of system you currently have in your RV or your travel trailer. This is just going to be the AC only, so you will have to make sure that you have the compatible air distribution box and thermostat as well. And we do sell those complete kits, whether it's gonna be for your ducted or ductless system.
So this uses the new R32 refrigerant. That's gonna comply with the new EPA regulations that took effect in 2025. That refrigerant is more efficient and environmentally friendly compared to the older R410A systems. But because of the new refrigerant, this is not going to be backwards compatible. So this isn't going to plug and play with pre-2025 systems as differences in wiring and controls typically require matching components for proper operation. So you will have to make sure that your thermostat, your air distribution box and other components that are tied into the AC are all going to be compliant and work with the new R32 refrigerant because this will not be backwards compatible with anything before the R32 refrigerant. Performance wise, you're gonna get consistent cooling throughout the space and this includes a thick gasket and foam pads that are going to sit between the AC and your roof. And on your screen there, I'm popping up a picture of the bottom of this AC unit just showing you those gaskets and pads there. So those do a couple of things. It helps seal everything up to prevent water leaks and air gaps. It's also gonna cut down on noise and vibration while it's running. Our cover here is made from durable plastic. That's gonna protect the internal components from weather and debris. It's going to be able to be easily removed as well. It's held in place by Phillips head screws, so if you ever need to take this off for whatever reason, cleaning it or maintenance or whatever, just remove the screws, pop the shroud off, and then when you're done, you can pop the shroud back on, replace the screws and you'll be good to go. But it's a nice cover. As you notice, it does have kind of this dark gray accent here. Kind of gives it a more modern look. It does include the wiring harness you probably saw before I hit the wrong button. And there it is again. So it's a six pin connector. This comes through the bottom front of the AC unit and it'll run through the opening in your roof, and then you'll plug that into your air distribution box. Installation is gonna be pretty straightforward. This is gonna bolt onto your roof. Again, this does not include any hardware though, so the bolts that are needed to mount this into place usually come with that air distribution box. This is going to fit standard RV roof openings of 14 and 1/4 by 14 and 1/4 inches. And it's gonna work with roof thicknesses from about two and 1/2 inches to five inches thick. So if you are looking for a complete kit, whether it's for the 155K or the 135K AC unit, we do have those available here at etrailer. Again, you'll just need to choose the kit that's gonna work either with your ducted or ductless system. It'll come with the appropriate air distribution box and thermostat and other components that you might need. But again, this will just be for the AC only. One final note, if you need help with installation, on this product page underneath the photo section, we have a link that will take you to our Installer Locator. Click that link and answer the questions that it has for you and that locator will find an installer in your area that etrailer has partnered with to do the installation for you. 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.
