Question:

I’m building out a cargo trailer camper and want to add AC, but I’m trying to keep the roof height down. Which one of these would make the most sense?

Hey Farid! For a DIY build where roof height matters, I’d start with the Advent Air low-profile # ADV76SR. It’s only 10-1/8 inches tall and gives you 13,500 Btu of cooling, so it’s a nice fit when you want a lower-profile black rooftop unit.

That AC is the rooftop unit only, so you’ll pair it with the Advent Air air distribution box with wall-mounted thermostat # ADV98SR. That interior kit works for ducted or ductless setups, which is handy on a build where you’re still deciding how you want the airflow handled. How thick is the roof on your cargo trailer, Farid? It will need to be 2-1/2" to 5" thick to meet standards for the unit.
