Question: how many tons will a dump trailer hold?
Answer: A 6×12 tandem axle dump has a 9990# GVWR, 24” sides, and an estimated payload of 7390#. Given that 6 x 12 x 2 = 144 cubic feet, divided by 27 = 5.33 cubic yards. This means the trailer will hold 5.33 yards of material if loaded even with the sides.
