After doing some research it appears the F450 and the F350 have about the same GVWR strictly for marketing purposes.
The F450 actually a Class 4 medium duty commercial truck that has a De-rated GVWR, so it can be sold as a Class 3 truck.
It actually can carry much more than it's DOT rated for. The wheels, tires, brakes, springs, axles and a bunch of other stuff is bigger than that of the F350.
But since both DOT and Insurance companies look at Class 4 trucks as commercial vehicles... Ford just changed the Yellow sticker numbers and sells them as pickup trucks.
Thank you Ford...
