actually it wouldn't be so bad to convert a bus to an RV, the trick for loading bikes would be to rob a slide up ramp off of a u-haul truck (sometimes they sell old stuff at auction) and attach it below the back door, my idea had bike storage towards the front, bunks in the rear, workbench/kitchen area in the middle/front. Another idea I had was an expanded metal storage box under the side to store gas cans and chemicals which require ventilation and shouldn't be kept inside. A small radiant LP heater would be good in the fall. Maybe an RV awning on one side so you could have a shady spot in the summer at the track, the racing rig schoolbus is my ultimate goal ;)
