Retrofitting Roof AC with residential Parts?
For those of us who have been around a long while, many of us will remember Professo95. At one point, I think he took the shell of dometic AC unit (because it was taller if memory serves) and then ...

When you have a small RV the available roof airs are too big! I know there is a 9K unit available but has many noise complaints and I cannot tolerate noise. I have never heard a roof air that I would consider acceptable sound wise.
The really sad thing about this is they duct roof airs but leave the motor and fans open to the living area. Simple cheap fix, duct the return air.
In humid areas the larger AC's cycle too much to keep the humidity down enough to be comfortable. Also without spending more money the larger airs will not run DEPENDABLY on a small generator. Yes I know about hard starts and micro air.
So I tried to convert an 8k LG window unit to a roof air. When 95 did his conversion the AC's were configured differently and without extensive mods I could not pull it off. Possibly there are other brands that may be dooable but I cannot spend all my time buying and disassembling AC's. Not a trained AC person but have the tools and take care of my own personal AC units. In hindsight my mistake was trying to utilize existing AC cover and base. If I do again will make the base, inside part and find something to cover it with outside.
So now have the 8k window unit where the rear bathroom window was with a 4E hard start in it and run it off a Honda 2000. This is not a duct tape and bailing wire job. I spent a bit on a proper welded framework to support the genny and AC. If I had room for the evaporator I would have installed a mini a long time ago! A mini modulates, a 9k mini would be perfect as it will modulate between 2k and 11k btu's, they also ramp up which would be perfect for a small gen set. Quiet, energy efficent, who would not want one? I have been running 3 mini splits in my 1300 sq ft house here in FL 24/7 and the electric bill this month is $64.94! Not an overly hot month.
