Well I don't know if it's going to work yet but I am gonig to take a window a/c unit and take the evaportor out of it and mount it above the rear door with a fan blowing out. Plus two vent for in coming air for the fan. The condenser and compressor will be mounted inside the bus along with the rear heater. I will have a fan for 12 volts and one for 110 volts. Then I will run two hoses between the two units. The way I have it figured I will work just fine.
