The axle rating is only one aspect in a whole lot of other calculations go into that final CCC rating (brakes, suspension, frame stiffness, etc.).
When I was looking for the truck with the highest cargo rating I was routinely disappointed in what I saw in the F450's glovebox.
I don't believe for a moment that any truck manufacturer is "downgrading" any ratings on their big trucks, they are always pushing the numbers higher to get bragging rights in that class.
The 450 is best for towing.
The 350 is best for cargo carrying.
But if you chose to "read between the lines" be prepared to live with the C$O$S$T of that decision.
When I was looking to replace my 2011 Ram 3500 12,200 GVW my conclusion was I either needed to go real big, ie Ram 5500 flatbed and then purchase a new/used daily driver too,
or
learn to live with a 14K rated 2016 Ram 3500 that I received 08/28. :)
The 14K rated trucks do great with the smaller but bigger :) campers like my AF 1150 but yay I'm not going to put a 4 slide Host or something on it and tow. And I can still drive my dually to work as my daily driver.
There are some companies that take F550 / Ram 5500 and fit a 9' truck box to it to make it look like a pickup but the $$$.
I really liked the Ram 5500 and flatbed but really just don't want to deal with another car/suv/truck at home to be my daily driver.
