CHASSIS FOR RECREATIONAL VEHICLES HAVING A TRANSPORT AREA FOR A FLUID STORAGE VESSEL

A recreational vehicle may include a chassis, an axle assembly, a floor, and a vehicle body enclosing living quarters. A fluid storage vessel may be supported in the chassis. The chassis may include a first and a second longitudinal chassis member each having an upper and lower edge, and an inner and outer face. Cross members have a first and second ends connected to the first and second chassis member, respectively. The cross members have an upper and lower edges extending between the ends. The cross members have an end height at the ends and a midsection height that is greater than the end height. A transport area extends longitudinally between two cross members, transversely between inner faces of the longitudinal chassis members, and vertically between upper and lower edges of the cross members. The fluid storage vessel is disposed in the transport area.
