Gene- Hopefully I'll weigh mine after our trip this weekend while it's still mostly loaded. After reading many posts on tire pressures, I think I can reduce pressure in the rear and still be well within the safe zone. The previous owner had the tires at 65 psi which is the max tire pressure, and I've left it set there. I know we are running well below GVW. We have a truck scale here at the quarry and I'll get front and back axles, for the four different wheel weights I'd would need a different scale.
