I've concluded I would like a second A/C in my bedroom. My camper is already prewired for one, and it would be the ductless kind. My local RV dealer quoted me $860 for the unit plus $160 for the knobs and such. $200 to come out and install. I found the same dometic 13500btu ductless a/c online for $419. It also has a heat strip addition for $52 which I think would be really great in the winter. Only issue is its "scratch and dent" meaning it has cosmetic damage. Considering it's on the roof idk how big of a deal that is. Has anyone purchased something like this before? How difficult is this to install by myself? Electrical skill is low to moderate over here.
