I have been using a Mototote Mtx carrier for a few years to carry a motor scooter on the back of my rv. I am about to trade in my rv and the new one has a rather recessed receiver. I didn't want to have to use an extension receiver which would have introduced another joint into the hitch setup. I was pleased to find that Mototote has the solution to this issue in the form of a Long Receiver Tube which provides up to 11" of additional clearance. A+ for MotoTote.
