Abstract
Abstract A vehicle trailer of the fifth wheel type particularly adapted for attachment to a light towing vehicle such as a pickup truck. The trailer body includes front, rear, and sidewalls and a floor which slopes downwardly to the rear of said trailer body at a substantial angle. The trailer includes a chassis supporting the trailer body, and the chassis includes chassis rails disposed beneath and parallel to the trailer floor. These chassis rails include an upper, forward portion and a lower, rearward portion and a wheel mounting sub-frame disposed beneath the lower, rearward portion of said chassis rails. The attachment arrangement includes a tongue having a rear portion thereof attached to and extending forwardly from the upper, forward portion of said chassis rails, and a tube or the like extending downwardly from a forward portion of the tongue for engaging a fifth wheel or ball on the bed of the towing vehicle. Because of its configuration, the trailer includes an elevated front body portion with the floor thereof extending substantially above and forwardly of the lower, rearward portion of said chassis. In use, the elevated front body portion thereof is disposed in overlying relation to the rearmost portion of the towing vehicle, and the wheels and axles are spaced substantially apart from said rearmost portion of said towing vehicle.
