Rolled over a scale today at 6300lbs. That was camper, recovery gear, propane, extra battery, spare tire, tire chains, tools, myself, half tank of fuel, plus random crap in the truck (Hi-Lift, compressor, blankets, etc.). There may be merit in a skeletal camper mounting frame, where I'd remove the steel flatbed (440lbs in itself). The truck has a GVWR of 6250, so I am over capacity. Good example of why a half ton requires attention to weight! To go camping, solo, I'd have an additional 50-100 pounds of food/gear, plus up to another 100lbs of fuel. 250lbs over gvwr doesn't alarm me, but tells me to watch it in the future.
Weight loss opportunities for this truck:
1. Flatbed removal: -300 lbs
2. Rear seat: ~-50lbs
3. Less "junk": ~-30lbs
