I was thinking about doing this on my park model in our bedroom. I have one 15k, but have a feeling it will struggle when it is really hot on a 42 footer. My camper does have 50 amp service but it is not pre-wired for ac that I can tell. I have not pulled the roof vent apart. I figured there would be a sticker on the ceiling saying it was pre wired like my old camper had. Luckily the roof vent Is close enough to my closet I think I can run the wire in conduit along my ceiling into the closet, down the wall, through the floor, under my camper over to where my breaker panel is. My neighbor is an electrician and looked it over and thought this would work fine. My question is about the roof vent. I was talking to the Salem dealer about the it being reinforced for an ac unit and they said that they install them all time and that should not be a concern with weight. The unit only weighs 100 pounds. I am not sure if I buy this.
