Granted if you loaded the rear axle to full rated 8,500-pound capacity you may exceed the 12,500-pound GVWR, but what would that really mean in practical terms? Specs on E-350 and E-450 are essentially the same except for heavier rear axle (9,600-pounds) and springs. Even tires are the same.

It seems some of these ratings are driven by need to meet government regulations more than actual equipment limitations.

I think you are on the correct track. The California EPA specs allow less severe SMOG restrictions on the larger E450 chassis that the lower weight E350 Ford. The 2017 Vegas 25.2 appears to be a 50 state EPA vehicle.
