I tracked it down. It was a pop up roof and deck option for the KampKing camper. Lifetime warranty too!
As far as I have been able to determine the company was started in the early 1960's and reportedly lasted until the early 1990's. The latest picture of one I found online that looked like these was a1968 model. They also made class C motorhomes on van chassis.
There was a pop out back option as well
