I used a Edge Star Portable AC in my restoration of my 1986 Scamp
. I have a custom deluxe so the pantry was only 12" wide that I was working with. I cut out the lower portion of the pantry and made room for the AC. I then made 2 straps out of nylon and a couple of plastic latches, all purchased from a local cloth store. The rear of the AC has a 3.5"x 3.75" square exhaust port. As luck would have it, the exhaust port was in direct line with the belly band seam. So, I regrouped and made a box out of sheet metal so I could off set my exterior exhaust boot (a residential dryer termination vent). The AC is 14" x 13.875" x 31". It only weighs 55lbs. and it works great. I measured the amp draw after the installation and it was 8.1 amps just like the spec stated.To complete everything I reworked the original door and made a small closeable cabinet above the AC.What is cool about this , is I can remove the the unit when not camping and put it to use in
our bonus room above the garage. Which is my wifes sewing room and it gets pretty warm up there in the summer months. This was all part of my plan.
I will try to post some photos. I will share more need updates later. Some are pretty cool. Like my door stop!
