1980's Four Wheel Camper in Helena, MT for $750. Found on craigslist. I called the guy and found out it won't fit my Toyota. It's an 8', 48" between the wheel wells, out to 64" between bed rails. The guy said it doesn't leak, all appliances work, no rips/tears in canvas. He's willing to negotiate on the price as well. No affiliation besides the two phone calls I made to him. Hell of a deal!
