I tow a 6000 lb Dodge Ram 4x4. Just towed it to California and back and still beat the trucks on every grade which is fast enough for me.
2015 and 2014 Ford E450s have a 22000 lb gcwr which makes them capable of towing 7500 lbs.
Forest River class c's are already coming standard with a 7500 lb hitch and tow rating to reflect these new numbers.
Expect other manufacturers to follow suit quickly. A 7500 lb tow rating is more than most low to medium end diesel pushers, a great selling point.
