synergy  syn·er·gy (sĭn’ər-jē)  noun
the working together of two or more things to produce an effect greater than the sum of their individual effects.

EarthRoamer Xpedition Vehicles epitomize the very definition of the word “synergy.”  Bill Swails, owner of EarthRoamer and designer of the first EarthRoamer XV-LT credits a large part of the success of the EarthRoamer XV-LT design to his education in Systems Engineering from Ohio State University. By Analyzing the structural and energy requirements of the XV-LT as a complete system instead of a collection of individual parts and components, the final vehicle is much greater than the sum of its parts and provides features and functionality unmatched by any other expedition vehicle or RV.

One Piece Composite Body

At the heart of this design is a one piece molded, sandwich construction composite body. Molded sandwich construction is used in yacht hull and aircraft manufacturing, but EarthRoamer was the first to use this technology in expedition vehicle manufacturing. Most expedition vehicle manufacturers use archaic and inferior glued-together, fiber reinforced plastic (FRP), flat panel  construction because it is much cheaper and they do not have the advanced technical capability required to produce one piece molded composite bodies. In addition to improved aesthetics, aerodynamics and thermal insulation, one piece molded XV-LT bodies have no seams to leak or fail structurally. Unlike other camper manufacturers, Monocoque  XV-LT bodies require no metal support structure. Internal metal framing on conventional RV and expedition vehicle bodies acts as a heat conduction path dramatically reducing the insulation capability of the body. Better insulation results in reduced heating and cooling energy requirements which makes solar and battery power viable energy sources. Additionally the strong monocoque XV-LT structure enables a large king or queen size over cab bed which dramatically improves living space efficiency.
