For a small family, or a couple out on their own, the 2008 Roadtrek RS-Adventurous is not too big, not too small-it’s just right. The vehicle rides on a 170-inch wheelbase and the body measures 22 feet, 9 inches long, 6 feet, 8 inches wide (without the mirrors) and 9 feet, 7 inches tall (with the roof air conditioner). The just-under-23-foot overall body length on a wheelbase approximately the same as a Chevy Crew Cab long-bed pickup, combined with a 27-foot turning radius, makes the RS-Adventurous a much more manageable drive than a larger motorhome. It can be easily maneuvered into the tightest of campsites.
Compact but well designed, the inner sanctum provides 6 feet, 5 inches of standing room, seating for up to seven passengers, a full kitchen, complete bath and sleeping arrangements for up to four persons.
The kitchen features a single-lever faucet over a stainless steel sink imbedded in the gorgeous granite counter top. Underneath the counter is a standard 3.8-cubic-foot three-way (12V/100V/propane) refrigerator that will hold enough perishables to feed a family for a long weekend without restocking. An optional built-in coffee maker was mounted underneath the overhead kitchen cabinets. Every spare inch of space not needed for something else in the kitchen area has been converted in storage, so there’s plenty of room for dry goods, cookware and other galley gear, too.
For cooking, you get a 1.0-cubic-foot, 1800-watt convection/1000-watt microwave oven under the counter, and a two-burner propane stovetop recessed into the granite with a hinged, smoked-glass cover. Both are standard equipment. And an auxiliary exterior propane quick-connect allows the use of a gas grill/stove outside of the RS-Adventurous for those who prefer cooking outdoors when camping.
Directly across the 28-inch-wide aisle from the kitchen is the bathroom. The head compartment includes a marine-style foot-pedal-flush toilet, a small vanity sink and cabinet, and a stand-up or sit-down (on the closed toilet lid) shower. It’s compact as well, but the compartment offers enough room for comfortable use of the facilities.
When traveling, the interior can carry up to seven passengers. There are two fully adjustable and supportive swivel captain’s chairs up front, and your choice of two lounge seats, or larger optional captain’s chairs that swivel in the second row. A small removable table can be mounted in the center of the four seats for dining or playing cards. The 19-inch flat-screen TV that’s mounted on a hinged extendable arm in the rear compartment comes with a remote control, and can be faced forward, or to the rear if you want to watch your favorite late-night-show host from the comfort of bed.
In the rear section of the RS-Adventurous, you get two choices: A power folding front-facing couch (that can seat three for travel) and two side-facing bench seats-all three come together and convert flat to a “king-size” (78 inches long, 69 inches wide) sleeping platform. Or you can have side-by-side (lengthwise) manual-folding twin beds offering 78×28 inches of sleeping space each. Another small table goes between the twins, or in front of the rear couch (when it’s folded up for sitting). A large storage area lies beneath the rear seating.
Two adults can sleep in the rear compartment when all the seats are folded flat and the tabletop is used to fill in the middle. The 5-inch foam cushions make a comfortable bed, but we found that where the cushions met in the center of the platform there wasn’t much support. A padded mattress topper that covered the cushions and didn’t allow your hip or shoulders to fall between cushions would help out here. To sleep a total of four in the RS-Adventurous, you have to get the optional folding mattresses that rest on top of the four front seats to provide two flat single-sized sleeping surfaces. The folding mattresses are stored during the day, or kept at home when not needed.
The new Roadtrek offers an external 110-volt hookup with detachable power cord, twin 6-volt deep-cycle (220 amp) batteries, a full systems monitor and a 750-watt 12/110-volt power inverter with a three-step 45-amp charger and remote on/off switch. A propane-powered remote-start 2.5 kW generator is optional, but would be on our list of must-haves to run the microwave and AC “off the grid.”
Creature comforts aboard include an 11,000-BTU roof-mount air conditioner (110-volt) with electrical heat strip, a 16,000-BTU automatic furnace, and a six-gallon propane-powered water heater with bypass.
Fluid capacities for the RS-Adventurous are 30 gallons for the fresh water tank and 24 gallons for the grey/black water tank. A 12-gallon/50-pound capacity propane tank is also standard.
Based on the Mercedes Sprinter van, the 2008 Roadtrek RS-Adventurous inherits all of the superb automotive features that come with it. The 3.0L V-6 turbodiesel delivers 154 horsepower and 280 pound-feet of torque, and is a thrifty little engine. It’s backed by a well-mannered five-speed automatic transmission that can be sequentially shifted so you can downshift and hold the gear, which is especially handy for taking advantage of the diesel’s natural compression-braking abilities when winding down a steep highway.
Other notables are the power-heated side mirrors, cruise control, four-wheel ABS disc brakes, tire-pressure monitoring system, 4.10:1 axle gear ratio, 150-amp alternator, 760-amp battery, 26-gallon fuel tank, and LT225/75R16E tires wrapped around 16-inch steel wheels. And Mercedes’ traction control system, and Adaptive Electronic Stability Program (ESP) that take’s vehicle load into account are also standard equipment.
The RS-Adventurous can tow all your toys, too. Equipped with a factory-mounted Class III receiver hitch, the Roadtrek is rated to trailer up to 5000 pounds.
Roadtrek’s new rig has all the comforts, conveniences and style found on full-sized motorhomes, but also offers the numerous technological innovations of Mercedes savvy. This combination makes the 2008 Roadtrek RS-Adventurous a great choice for the new-millenium RV camper.
First and foremost on most folk’s minds these days is fuel economy. We experienced, depending on road conditions and the load we were carrying, anywhere from 16 to 21 mpg during our nearly weeklong evaluation.
Granted, the RS-Adventurous is very compact inside, and built for outdoor family weekends, or for a couple to spend an extended period of time in, but the rig’s remarkable features, superb design, and conservative fuel-consumption numbers will strike a cord among many camping families that don’t need or want a motorhome the size of Yankee Stadium.
