My '90 Westy is already white, the windows tinted with heat absorbing material, the
curtains in the back are closed all of the time and the walls, in addition to the
original fiberglass, have foilfaced bubble wrap where I was able to put it. It was
always much cooler in the back, so much so that my dog would refuse to get out at rest
stops, once the sliding door was opened and she felt the blast from hell, also known
as summer in the Southwest.
My modification was to bring more of the cool air right up to the front where it dumps
right on me. I made a duct from 3" diam. flexible aluminum vent duct. It expands from
3' to 8' and holds it's shape. It's plugged into the far right opening above the back
seat, routed over the sliding door and attached to the back of the passenger seat
headrest with the opening facing the drivers seat. A second duct could be made on the
opposite side, for the passenger seat. It works great. I have since dressed it up by
covering it with a gun sock, a stretchy, knit gun cover. They are 55" long, so it took
two. Open up the closed end, stitch it so it won't come un-raveled and pull it over
the alum. duct. It fits very snugly.
I have photos of the duct in place, before I covered it, if anyone is interested.
