Differences between 2.5 and 5 ton sheetmetal ?

[Al Capone]

So cab and doors are same . Wonder why fenders and front sheetmetal different ? Is frame longer in front ? Are the multi fuel engines and radiators same ?

The frame is beefier, and longer, as is all the sheetmetal from the firewall forward, the engine is basically the same block, but the pistons, injector pump, and injectors are different. The radiator is bigger than the one on a M35A2. If it has a winch, the winch is twice the rating of the M35A2's. Hope this helps.
