"What is Weight Distribution?
Try to think of a Weight Distribution Hitch System as a bridge connecting the towing vehicle and the trailer. It has an adjustable under truss system called spring bars that join the “V” of the trailer to the hitch head and the receiver hitch to evenly distribute the weight.
The head bolts to the shank to ensure proper height and the shank slides into the receiver hitch which is bolted to the towing vehicle. The weight is then more evenly distributed between both axles of the towing vehicle and the trailer itself".
I see nothing wrong and see where a WD would be OK for ANY type trailer towing behind a motorhome. Above is from Reese Hitches. Doug
