I haven't kept up with the details of the F450 pickup in the last year couple of years. I know that it was originally an F450 cab and chassis modified for a pickup bed. Ford had so many complaints about it being heavy with poor fuel economy and low speed rating (due to the 19.5" tires) that after about 2 years they went back to the F350 with a beefier rear axle for towing and a wide front but otherwise all the same limitations as an F350.

You’ve got it in reverse. There were only a couple of years that the F450 didn’t have the heavier suspension/tires. I think 2012-2013, but maybe someone else knows.

The F450 pickup started with the 2008 model year, and has never been just a cab and chassis with a factory installed pickup bed. Cab and chassis trucks have straight frame rails behind the cab. The F450 pickup has never had that.

The 2011-2014 F450 pickups were almost identical to the F350’s of the same model year. I honestly don’t know what the difference between them was other than the badging for those years. They didn’t have 19.5” tires, didn’t have the Dana S110 rear axle, or the bigger brakes that went with those. Not sure about the wide-track front axle for those years, but the 2008-2010, and 2015-2016 F450 pickups all had 19.5’s, Dana S110, bigger brakes, and a wide front axle.

I’m not as familiar with the 2017 and up F450 pickups, but it appears you can order them with 19.5’s, or some other more traditional size tires, which I would think would directly affect the axle, brake and suspension components that would go with the non-commercial tire sizes.
