Abstract: A frame portion is provided for the upper deck of a fifth wheel travel trailer, wherein the side wall or perimeter beams are placed at the same elevation as the intermediate floor beams, preferably formed from the same dimension beams. Where additional reinforcing is needed along the frame perimeter, horizontally extending beams are used to supplement the side wall beams. Additional structure for receiving, resisting, absorbing, and/or reducing towing stresses, loads, and torques is formed in the forward portion of the upper deck, and can include a built up portion of the frame which is forward of the flat floor slide-out mechanism.

Abstract: A fifth wheel trailer of the type designed to be towed with a towing vehicle having a vehicle hitch assembly includes a trailer body having an elevated front portion, and a mounting arrangement extending downward from beneath the front portion. The front portion of the trailer body has a generally convex forward surface. The trailer further includes a trailer chassis supporting the trailer body. The trailer chassis includes a forward portion supporting the front portion of the trailer body. The forward portion of the trailer chassis has a pair of side frame beams that extend along the sides of the trailer chassis. The forward portion of the trailer chassis includes a curved forward edge beam that is joined to the forward ends of the pair of side frame beams. The curved forward edge beam generally matches the curve of the front portion of the trailer body and provides support for the trailer body.
