The F450 pickup has better towing capacity than the F350 but the payload is eaten up by the heavier running gear. The cab chassis version of the F450 has up to 16.5k lb GVW but expect 10k lbs plus for an empty fully outfitted truck.
This was the reason I jumped to the F550 and 5500 which have 19.5k lb GVWR yet don't weigh much more than the F450. I plan on a 6k lb TC, 500-1000 lbs of batteries, 500 lb front bumper with winch and close to 1000 lbs of tongue weight. I'm sure I could have scaled back to get within 16.5k lbs, but I wanted as many options available to me as possible in a compact chassis that still offered 4wd and crew seating.
