help pricing this truck

[D13]

Check me on this guys, but in this vintage a crew cab would be a 1 ton or at least a heavy 3/4. Now I'm looking at the 5 bolt wheels and low profile tires and thinking someone has made a Suburban with a box on the end. I question if the frame was shortened, it looks more like a half ton frame was stretched (5 bolt hubs?). So now we have a truck with seating for 6 and load capacity for none. i can't imagine trailering a 5th wheel or anything bigger than a pop-up. The rims and tires alone limit the load capacity (and quite frankly I'd be scared to drive it down my Michigan roads with those tires - too low).
10K for a really cool car (which it is) seems about right. It's worth is not in the truck, it's in the neat factor.
