Rebuild old flatbed, or start from scratch?

Excessive? Yes, very much so...I know this. But I also plan on pulling a trailer behind this with one of the 4x4s on it, and I have a thing for vintage iron. It will be getting repowered with a modern drivetrain, and yes, I know many will consider a modern truck to be subjectively "better". Up until last fall, I was daily driving a '62 truck despite having an '05 Ram sitting in the driveway. Yes, I probably have plenty of screws loose upstairs :D I know this truck will be slow, it will ride like it doesn't have any kind of suspension, shifting will get old, gas mileage will be horrible, etc etc etc. Plenty of people told me the same thing about the '62, and the Suzuki Samurai that I've been driving to work the past few weeks too. I like being different :P

Right now, I'll have 6-8 inches of clearance between the cab of the truck and the camper, and a total height of roughly 10.5 feet, with a 70-something Six-Pac camper. It's pretty small, and stripped down inside. Barely even sank the suspension on my 1/2 ton truck. A while back I had found a 70-something Amerigo camper that looked like it would right at place on top of the International. Unfortunately, by the time I remembered to call the seller, it had been sold. I'm hoping to find another at some point in the future, or maybe something like an Avion.
