There's two factors at play here. First, and perhaps more important, is the length of the overhang. Let's say you have two motorhomes where both are on the same chassis with the same wheelbase, but one is 24' and the other is 27'. As there's 3 more feet behind the wheels, there's a lot more chance for interference - the hitch will be in contact with the ground more frequently.
Secondly, because the GM chassis front end rides lower than Ford, that increases the GC (ground clearance) at the hitch, given the ride height is the same at the rear axle. If you have two motorhomes of the same model on GM and Ford with the same/similar WB (wheelbase), the GC of the hitch will ride higher on the GM due to the lower ride height, again, given the ride height is the same at the rear axle.
