I am seeing if anybody has run two window ac's in the back doors of their vans. I finally seen a Dodge Ram conversion van with two air conditioners in the back doors of the van, but they looked like small btu ac's. I am running two window ac's in the back of my 1990 Ford Econoline van. One is a 10,000 btu a.c. and the other is a 8,000 btu a.c. so combined the van has 18,000 btu's to make the inside of the van a meat locker.
