My concern is the legal aspect of being so close, or barely above the legal limit.
Legally there is no difference between an F-250 and an F-350. The manufacturers do not set the legal limits. That's what your legislature does. The 10,000 lbs you referred to is not a legal weight restriction. Ford, GMC, Chevy, Dodge nor any other truck maker determines legal weight. They don't make the laws.
Generally, the legal weight limits are 20,000 lbs on a single axle. You're not anywhere close to the legal limit with your 5er nor will you be with either the F-250 or F-350.
Some states register vehicles based on the weight they haul. For example, if you register your truck for 10,000 lbs then that's the max weight you can haul. But if you want to haul 14,000 lbs then you buy registration for the increased weight.
But in either example, the manufacturer has nothing to do with either.
