Thanks Rob! Makes perfect sense. I'd forgotten about the weird obsession with customized vans back in the '70s.
As a kid, I had two customized van kits; one by Revell and one by Monogram. The Monogram one was empty inside and I remember it came with Chevy symbol side windows that you had to carefully cut the sides of the van to install. I just glued them in place.
The Revell kit included a removable roof and I think it had a bed, TV and other "cool" custom features inside. It was molded in a "midnight blue" plastic (dark blue with sparkles) so no need for painting.
These were the two I had and built back in the day:

For some reason, it "had" to be a Chevy van or it wasn't "cool."
