After a long drive or a full day in the sun, this 15,500 Btu system cools your RV without long, uneven cooldown cycles. It fits larger trailers and RV interiors where higher cooling capacity keeps temperatures from lingering.
After a long drive or a full day parked in the sun, your RV can hold heat in the roof, walls, furniture, and cabinets well into the evening. This 15,500 Btu air conditioner delivers 430 CFM of airflow to help bring cabin temperatures down and keep cooled air moving, so the interior feels more comfortable when it is time to relax.
A good rooftop AC install needs more than cold air. It also needs a solid seal where the unit meets the roof. The thick, collapsible gasket helps block rain and hot outside air from entering through the opening, while the foam pads help cushion the unit and reduce vibration at the mounting point. That helps the AC run securely while keeping the cabin drier and quieter.
In a non-ducted RV, cooled air comes straight from the ceiling assembly instead of traveling through ductwork. The included AACNDC air distribution box has adjustable louvers on the front and back so you can move air across the cabin. That gives you more control over where the cool air goes in the area where the AC is mounted. The removable, washable air filter traps dust and debris before it reaches the fan blades to keep you AC unit cleaner.
This system keeps the controls simple by building the thermostat into the air distribution box, so there is no separate wall thermostat to mount or wire. The flat touch-control panel lets you adjust mode, fan speed, and temperature right from the ceiling assembly, making it a straightforward setup for non-ducted RVs where the cooled air comes directly from the unit.
Replacing a rooftop AC is easier when the main pieces are designed to work together. This system uses a bolt-on installation and includes the wiring harness needed to connect the rooftop unit to the air distribution box. Once installed, the uv-resistant hard plastic cover can be removed for maintenance and cleaning, so you can access the unit when it 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. The air distribution box is also prewired for the optional heat strip (ADV34QR) which can help take the chill out of the air on cool mornings. These upgrades are not included, but they give you a way to build out the system for the way you camp.

Hey Brendan! Yes, the brown wire is what you'll use to wire in your furnace! I'm glad you're nice and cool and enjoying your new AC :)

Updated review, once parts arrived after being reshipped, install was straight forward and it cools really well. Actually works better than the Dometic I was replacing. So now I give it five stars!

Your camper looks amazing for 30 years old! I hope you can enjoy all that cool air this summer, and maybe a little bit a piece and quiet along the way.

Cool camper Robert! And I think you will be perfectly fine. If you do start noticing moisture though, you can always add some caulking to the seal. That will definitely get it all sealed up! Thanks for the tip as well! I wasn't aware the touchpad was that sensitive. Or not sensitive. You know what I mean.
