Drove a '69 C10 Chevy for years as a company truck in construction. Everyone liked to fuss about the coil springs on the rear of those things.
When the truck was at least 10 years old, had to move a mess of 10" concrete blocks from one job site to another. Stuffed all we get on it. The step bumper was about 6" from the pavement and we pondered how much weight was on the poor ol' thing.
Later that year I lined the bed with cardboard and went for a load of fresh cold patch to repair some potholes in a parking lot. When I pulled on the scale, had
2100lbs of cold patch on it. Bumper was a good 12" off'n the pavement that time, so figure the blocks must've been close to a ton?
Guessing that old critter probably had a rated "payload" of far less than many of today's new half ton trucks with far better rear springs? But it regularly toted well over a half ton without complaint.
