Hi Folks, Some of you may remember I was talking about installing a roof A/C on my camper before I went on my cross country trip. Turns out I didn't want to spend the money on something I may not use often. Needless to say that was a mistake as it gets pretty darn hot in the southwest in September. Well, this winter , while it was in storage , I devised an idea to use my window A/C without it looking too redneckish. I took out the small upper front bunk window, made the opening larger and re-framed it.Then, I built a plywood box and fastened it in the corner. It's anchored to the ceiling rafters and 2 walls. The box is made to exhaust the hot air out the center and draw cool air in the sides. I found a metal Louvered grill that I adapted to work. I also had to run a new outlet to that area wired off my existing 20 amp breaker that was intended for the roof air. I also bought a drain kit for the A/C and run the tubing down the vertical chase they used for my shower plumbing, straight down through the floor to outside. it all works well and I can't wait to try it out in the summer heat. I think it looks almost OEM.
