A method of manufacturing a vehicle-body structural component includes: forming a cylindrical molded body made of a fiber-reinforced resin by molding a continuous fiber impregnated with a thermoplastic resin into a cylindrical shape and curing the thermoplastic resin; disposing a component in a space on an inner peripheral side of the molded body; and heating at least a portion of the molded body to melt the thermoplastic resin while maintaining continuity of a fiber in an axial direction of the molded body and continuity of a fiber in a circumferential direction around an axis of the molded body, deforming the at least a portion of the melted molded body from an outer peripheral side toward the inner peripheral side of the molded body to form projections projecting toward the inner peripheral side so as to come into contact with the component, and then curing the thermoplastic resin again.

One or more aspects of the present application relate to the configuration or management of an integrated component that provides structural component functionality for a vehicle, such as a cross member that absorbs loads placed on the vehicle. Additionally, the integrated component illustratively further provides air reservoir functionality that for one or more additional vehicle components. By way of illustrative embodiment, the integrated component can illustratively provide structural component functionality associated with a cross member mounted between shock towers and air reservoir functionality to provide compression air such as for active or semi-active vehicle suspension systems.

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 at least a portion of the transport area.
