per Ford, it's 5yr/100K on diesels F250-450. Taking a base model XLT as an example with no additional options, it is $55.480 for the F350 & $58.810 for the F450. The big differences I can tell are the F450 has:
Diesel exhaust brake
Widebeam front suspention
1.1" larger front rotors, 1.5" larger rear rotors
upgrgaded braking with Hydroboost ??
19.5" rims
cab steps & splash guards.
Either will pull your trailer, and with only 500 lb difference in payload in favor of the F350, it seems the F450 has more available to help stop the load.
All SuperDuties have diesel exhaust braking. The F450 has a 14.5K lb rated rear axle over the 11K lb in the F350 in addition to the 19.5" wheels.
