Inside, we chose Sportsmobile's most popular floorplan, the RB-50, because of its abundant storage space and open layout. Incorporating the company's 3.5x8.0-foot popup/fold-down roof provided a more aerodynamic profile for improved fuel economy when driving on the highway and a lower center of gravity off-road. When it's time to make camp for the night, the top's built-in electric motors raise the roof at the touch of a button to provide a full 6.75 feet of stand-up height. With a roomy upper bed and fold-out sofa, it can easily sleep four adults.
All the comforts of home are here, too, including a two-burner propane stove, microwave, 2.7-cubic-foot refrigerator, kitchen sink, electric-flush porta-potty, propane furnace and water heater, 10-gallon fresh-water tank, and 115-volt AC power. After a long day on the dusty trail, swing open the rear doors and attach a bow-shaped rod with privacy curtain, and you can enjoy a hot shower.
Because engine, tire, and wind noise can wear on occupants over the long haul, the crew at Sportsmobile added several hundred pounds of sound insulation to walls, floors, ceilings, doors, and the inside of the engine cover.
Communications are handled by a Midland Radio 40-channel CB with seven NOAA weather channels. A custom-installed Beltronics RX75 Plus remote-mount radar detector helps keep the driver out of trouble when trying to make time. The job of protecting all these goodies falls to a Viper alarm with GPS tracking capability.
Outside, the Ultimate Adventure Vehicle sports lightweight aluminum bumpers with locking storage compartments perfect for stowing recovery gear. A 12,000-pound winch wrapped with 100-foot plasma winch cable adds peace of mind for off-pavement excursions. The rear-mounted spare-tire carrier opens up space for an under-floor storage compartment, while rear baskets carry jerrycans (two for water, two for fuel).
