this is the most amazing compact motorhome; I can carry 3 sets of Race Ramps in the upper berth ; it turns out I only need the 11' long 11" rise set if I have a level ground to load and unload the car from the trailer; I have two small set in case I need to raise the front wheels to prevent the center of the car from being high centered as it go over the apex of the ramp and the trailer deck
