It's clear that the 14K GVWR on the pickup models compared to chassis models is a made up number. My 2010 F450 has a 14,500 GVWR. I like the truck, but I don't believe that newer lighter trucks are less capable. ;)
My F450 is one with 19.5s. They had more room for larger brakes with the exception of a few years that had 17s. Fwiw, I've read here that the rear diffs are the same on F350 DRW and F450s for a few years. That would be something else to check. The chassis cabs have the same diffs as far as I know with a lot higher GVWR.
That being said, I have no doubt my diesel F450 with 4.30s is very capable and could carry any truck camper or pull any fiver with ease. I probably could even carry a lighter popup. :D
Seriously though, I bought it used a few years ago just in case I ever wanted a giant fiver. I've paid in fuel costs, but it stops with the TC on probably about as fast as my Mustang GT. The brakes make my wife extremely confident. There was one panic stop with her driving that convinced her that the truck is totally awesome. She never had that feeling with the previous truck.
Actually for a number of years the F450 had a Dana110, I'm under the impression that for a few years it had a 16K GVWR as well.
The problem that many of us have with GVWR is that it is not based on engineering. I pity the folks that live in jurisdictions where it is important.
