Upper deck flat floors for fifth wheel RVs
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.
1 . A fifth wheel travel trailer having and flat floor slide-out within its upper deck.
2 . A fifth wheel travel trailer having a frame with an upper deck portion formed from horizontally extending side beams at the frame perimeter and intermediate center beams, the vertical height of the side beams being no greater than that of the center beams, and a slide out assembly being mounted in the upper deck which allows for flat floor positioning in the extended position of the slide-out.
3 . The fifth wheel travel trailer according to claim 2 wherein perimeter reinforcement of the upper deck portion of the frame is provided by horizontally extending support beams adjacent to and interior of the side beams along the frame perimeter.
4 . The fifth wheel travel trailer according to claim 2 wherein the frame includes a structural device forward of the operation of the upper deck slide-out portion for directly receiving, resisting, absorbing, and or reducing the towing forces which cause deformation stresses, loads, and/or torques.
5 . The fifth wheel travel trailer according to claim 3 wherein the frame includes a structural device forward of the operation of the upper deck slide-out portion for directly receiving, resisting, absorbing, and or reducing the towing forces which cause deformation stresses, loads, and/or torques.
