Hello, new guy here. A friend of mine has a very nice Vanguard camper on a 1976 F-250 that he wants to sell. It's in great shape, no leaks ever, everything works, and it runs like a top. I'd like to have it but I'd have to fly up to Canada and pick it up, so it would be a road trip on the way back. The truck is not an issue, he'd have it serviced and ready to go and I know old Fords like the back of my hand. The camper, on the other hand, is a different story. I've never owned one of these before and I have no idea how to operate the systems. I can't find much on the Vanguard brand, and what I have found is mostly later model trailer campers. Can anyone ID the camper in the pictures, and is there a source for PDF manuals for it? Thanks.
