Spare tire
Roadmaster is a terrific product - expensive but it will outlast several RVs. The pass through receiver would only work for towing if you don’t need a high/low adapter. It seems you are not allowed more than two hitch pins when towing. At least with my system. Also the unit reduces the tongue weight by 50%. So it’s great for a tire and bikes or my pair of mopeds but probably not a trailer.
