Caravanner 22' has the same bad floor issues so cab off is necessary. Intend to
put 14" high extensions on outriggers with circumferential top plate. While cab is off, radius the wheel openings, chop the axle ends and modify to independent air lift suspension. Suspension set to normal road clearance or 11" of lift for off road. No problem to kneel to ground as have added new front electric jack which fully retracts. Do not know how to raise ball height to allow full lift and still keep rig level. Will replace the belly pan with .60 EPDM rubber . foam the original frame cavity and then add new floor at new 14" height. thoughts?
