My 16' dump is rated at 12,000 GW and my 10' dump at 10,000 GW. 16' weighs 3,800 lbs 10' weighs about 2,500lbs So, I can haul about the same thing in either one which is sad. The 16' I would expect to be 14-16,000 GW. Is it possible to change out the axles to bump up the GW? I'm pretty sure it is how it is and nothing I can do about it but thought I would through it out there.
