Years ago, like 20, I purchased a Vintage Air evaporator and installed it in
a 23' 1973 Glacier under the dinette. The problem was having 5 of us almost
always in the coach and no one could sit in the dinette while it was
running. It froze their bottom half. And was mostly useless for those who
mattered up front. So I sold it to a friend. I don't really know how he used
it but I bought it back 5 years later. And installed it under the dash in
front of the engine compartment. Bob of Las Vegas can tell us if it is still
working.

I recently listened to Dave of Michigan and his modifications. So, I have
drilled two 3" holes in the front cover plate of my late 74, registered 75,
26' Avion and run tubes into the cabin. I have not figured out where I want
to land the outlets yet, but I know this, the tubes blow big time. I have
eliminated outside air, relocated the radiator overflow container, installed
a ball valve, fixed in place several vacuum pod openings as well as made
other changes. BUT, as of now, I have not had it on the road on a 100 degree
day. Will it help...big time. Will is solve the problem, time will tell. I
am still looking for a truck rooftop evaporator with a distribution system
for vent air as well as AC. But this I also know, the GMC compressor will
handle two evaporators easily and then some.
