Bigfoot Class B camper van
We just bought one. They were made in 1996-1997 only; built on a Ford Econoline E350 chassis. Rear dinette converts to a bed that's a bit smaller than double size, a third seat converts to a narrow single berth. One piece fiberglass enclosed bathroom that includes a shower/sink/toilet, which is wonderful: no showering in the hallway.
According to Bigfoot expert Mark Holmes, they were built as a touring van. Some insulation but of course nothing like the Bigfoot campers have. We've added a Fantastic Vent to replace the cheezy Ventline vent, and now are struggling with the seller (Johnson RV in Sandy) to get the mold-saturated rear cushions replaced.
I notice there's another Bigfoot Class B owner on the forum, so at least two are extant. Actually, one sold on e-Bay this spring as well.
We're still learning...
