People need to understand payload is a joke on the 350, 450 and 3500 DRW’s. WHY is it LESS on the 450??? Simple answer they are all self limited to the Class3 14,000# GVWR. 450 weighs more so less payload remains after subtracting trucks factory weight from 14k.
If they make GVWR higher they put the trucks in Commercial Classification and licensing and insurance costs increase.
Simply tow within your RAWR and pay for extra tonnage if you go over 14k.
Your argument for why the f450 has less payload than the 350 seems reasonable until you look at the rear axle weight rating of the two trucks... The rear axle of the f450 is rated lower than that of the f350. Unless I was towing off road and over a 30,000 lb trailer I would not want the f450's gear ratio. In my opinion the f350 is a better suited truck for a large RV than an f450.
