That looks like it could have a handy home in the back wall of the bedroom, exhausting air through the rear cap. Built into the cupboards above the bed. Heavy at 100 lbs, two sizes - 9K and 12K but, both will run on a 15 amp breaker and 14 gauge wire, both under 10 amps running.
I've been thinking about what I think is called a "mini-split", with an evaporator section mounting inside and the condenser section mounted in the engine compartment where the bus AC compressor used to be.

The site has the mini-split at a good price also-better than e-bay listings...4 bus nuts I've talked to in person have them and are more than pleased with end product..One local friend is a Hvac guy and he used two 12,000 in his 8..total satisfaction with end result...the thru the wall would prob do the same..just select correct product for you application...I'm using Mini-Split.....Bob
The main thing I liked about the wall unit is that it does not have any external freon lines. With it sealed from the factory (like a refrigerator, or roof top A/C) there is less likely hood of leakage problem. Then you don't use any basement cargo space or have unsightly warts on the roof. Good Luck, TomC
Very nice and very compact. But will it work doing 60 mph? In and out ducts out the side of the bus may need opposing air scoops.

One other thing to look out for; the upper ambient temperature for the air conditioner is listed as 99 degrees Fahrenheit. That won't cut it in Arizona in the summer.
The mini-splits that I've been looking at range from 115 to 130 for the upper ambient, which would be another matter. The higher, the better, for Death Valley or Bullhead City this time of year.
Good luck.
