I was at SEMA this year and was looking for units that might fit, REASONABLY WELL, under the dash but, after talking with a few of the AC authorities, I think I may graft an AC unit behind the dog house and then vent it appropriately, forward and reverse. I can mount the controls on the dash as well.
I'm open for ideas and suggestions. I'm thinking initially, this would be the easiest unless you know of a good small unit that fits well under the dash, and can take care of the rest of the van.
Sidenote* I helped a buddy fab one under the seats of a '36 Chevy truck a while back. Worked fine.
Thanks again!
