It’ll almost definitely be a ton of work, unless it’s been restored, in which case it’ll be a ton of money.
They’re really cool, really fun vehicles. They’re also 40+ years old, and that includes the canvas, wood, fiberglass, everything. What I see when most people buy them is the need to fix a rotted floor, replace the canvas, replace any appliances, just for starters. That doesn’t include the work a 40 year old truck needs.
They’re awesome, but you need to be ready for a serious project if you want the enjoyment of owning one.
I had one for a while. I completely gutted it before it was really ready to camp. Drove it 30,000 miles in about 2 years though, and it never let me down.
