Before I purchased my unit, I contacted Dometic tech support because I could not determine what the BTU rating based on the documentation. They said that it was a 13.5k. A few websites show this unit as 13.5k, but most like Camping World, do not indicate it. I use this rooftop unit as a 'backup' or compliment to my current basement a/c. It works wonderful. If it is in the 80's, I can use only this unit very easily. But in HOT Arizona summer of 115 degrees, it works great in conjunction with the basement air. It does not have a heat pump or heat strip though. :(
This is the unit for sale at Camping World:
