This is the standard length MotoTote square tube which goes into the vehicle receiver/hitch - the MTX Platform and rest of the MotoTote carrier attach to this tube.
Distance from vehicle with this stock MotoTote receiver tube is adjustable from 11 to 20 inches. This is measured from the hitch pin hole to the bike centerline. If you need a longer tube for vehicles with large spare tire or RVs with the hitch recessed under the bumper, see RTBL - Receiver Tube Long.
