A mobile home chassis having a generally flat rectangular shape with a front, rear, sides, top, bottom, and midpoint between the front and the rear. The chassis has two girders arranged parallel to each other and extending between the front and rear of the chassis. A plurality of joists is attached perpendicular to the girders and spaced apart from each other. An axle assembly is releasably attached to the bottom of the chassis between the midpoint and the rear of the chassis and a hitch assembly is releasably attached to the bottom of the chassis and extending forwardly from the front of the chassis. The releasably attached axle assembly and hitch assembly may be removed at the installation site of the mobile home and re-used, thereby reducing the cost of producing mobile homes using the chassis of the present invention.

The recreational vehicle trailer chassis includes two main frame rails running front to back with a series of perpendicular connecting main cross-members to form a structural configuration increasing the torsional rigidity of the frame. The main floor and support framing has a front and rear living area generally divided by the direction of structural trusses. Above the rear and middle main frame rails is the rear and middle floor framing formed with a plurality of frame members. Between the rear and middle main frame rails and below the rear and middle main floor support framing are structural web beam trusses perpendicular to the main frame rails along with vertical support columns that connect the lower main frame to the rear and middle living area floor framing further increasing structural torsional rigidity. Above the forward main frame rails and vertical support columns is the front floor framing with a plurality of frame members along with structural web beam trusses running parallel with the forward living area floor. Outward from the main frame rails and vertical floor support columns is the front to back side saddle framing to allow access to the basement area internally and externally. The furthermost forward floor framing sections are where the hitch structure and hitch are located.

The invention relates to a heavy-load vehicle comprising at least two partial vehicles, namely a frontmost partial vehicle and a rearmost partial vehicle, said frontmost partial vehicle having connecting means, and said rearmost partial vehicle having counter-connecting means adapted and configured for cooperating with said connecting means, one of said connecting means and said counter-connecting means including an inner telescopic member guided in a hollow outer telescopic member in a telescoping manner. According to the invention said hollow outer telescopic member is integrally formed by a tubular or box-shaped central part of a partial vehicle frame of one of the partial vehicles, said hollow outer telescopic member and said inner telescopic member cooperating therewith being parts of the same partial vehicle.

A front bolster and frame connection system for an intermodal chassis including a front bolster, a front gooseneck frame extending from the intermodal chassis having beams, mounting tabs attached to the front bolster, mounting tabs attached to the front gooseneck frame, a front gooseneck frame mounting plate welded to the end of the front end of the front gooseneck frame, and angle braces attached to the mounting tabs. The angle braces connect the bolt on front bolster and the front gooseneck frame. A retrofit kit and an alternate embodiment are also provided. The bolt on front bolster design of the present invention requires minimal cutting or grinding to remove and minimal welding to replace. The bolt on front bolster adds considerable value to operators in the intermodal market by facilitating service and eliminating chronic issues.

A composite boat trailer for use in saltwater. The beams, bolts, hangers, fenders, guide poles, suspension, and bunks of the trailer are formed from a composite material that cannot rust or corrode. The trailer employs a manufacturing technique that reinforces all beams to distribute forces anticipated during the movement of a boat on the trailer at highway speeds.
