IF they can get below max gvwr, staying with a 3500 makes a lot of sense. Especially considering how horrible the selection of 40" military MPT tires is. The Goodyears are $2000 a tire and huge pain in the ass compared to standard LT tires.Would still rather it be on the F550/5500 platform for tremendous margin of safety at minimal additional cost. Downside is parts are slightly harder to find vs a 1 ton chassis? Drivetrain parts will not need replacing as often as they are right sized for the 40s and weight I would guess.
