Rooftop Camper Air Conditioner (AC), 13500 BTU. Used: $350

-Upgraded to a residential mini-split heat pump during an electrical retrofit.

-Haven't used camper in 2 years, but it worked last time I ran it and it has always worked.

-Came factory on my 2010 KZ camper trailer, which sees about 2 weeks of use per year.

-Fits standard RV rooftop opening and runs on 120V.

The RVP 8000 series AC model is effectively a Coleman Mach air conditioner, as RVP is the parent company and owner of the Coleman.
