Ok so here it goes. I am in the strictly planning stages right now. I own a 1986 StarCraft 17SLE and I am looking to do a rehab/remodel of it this upcoming off season. During that time I am going to add a new subfloor, new flooring, new storage boxes, bunk bases, new bunk pads, etc.. I was also looking to add an AC unit. The question is, should I make the ice box area an enclosed AC unit by using a window AC unit, or try to add supports to the roof for a roof mounted AC unit? I am not sure if the lift system would be able to handle the extra weight. But I know I would have to put some sort of support (1/8" angle iron across the top of the roof or similar solution) on the roof since there is not any heavy duty support built into the roof. Any and all suggestions are welcome. TYIA!
