Looks like an RB, but I can't tell for sure.
We have decided to make our 2002 Sportsmobile available for sale. It is a custom built 4x4 camper van built on a Ford E-350 chassis including a 7.3 liter diesel motor, power windows, air conditioning, etc. This is a very capable rig with a Quigley 4x4 conversion. Mileage is currently 189, 203. Very heavy duty Road Armor bumpers front and back including jerry can box, spare carrier, and front winch mount. Top pops up for additional sleeping with screened and vinyl covered windows. Very well suited for off-the-grid adventures, including a fridge, 12v DC house battery with inverter for 110v AC, kitchen sink with onboard potable and grey water tanks, portable toilet, propane heat, Fiamma awning, privacy curtains, camp table, cabinets and storage. This rig has been used for adventure and is not in showroom condition, but is super reliable and still looks great. If this is something you would be interested in, please contact us to arrange a viewing.
