Ok, I looked up online, and I'm getting conflicting info.

I would like to know how much volume will fit in a long bed srw 4wd 3500 with no bags.

The tires have plenty of load capacity.

Previous trucks I've had 2nd Gen and 3rd Gen had bags, and I was probably overloaded by weight due to those years' rating, but I can't remember how much I put in the trucks.

In my current truck, I've had pellets on a pallet that was 2000k, and the truck was squatting almost 2 inches.

I'm building raised beds for my dad a power wheelchair, so I need to do 6 cubic yards and want to make the fewest trips.

From pick-up spot to his house is 6 miles.

If I'm not spilling over the rails, how many cubic yards would this be?

Thanks for the help.
