Upper Deck Slide Room Opening
If a fifth wheel has a Lippert In-Wall slide opening in the upper deck area, the bottom cross tube should
be equal to, or longer than, the header tube. If additional height is needed, the manufacturer will need to
add another cross tube that is .060" (1.5mm) gauge minimum and add vertical supports for strength. The
supports must be a minimum 1" x 1” (25.4mm x 25.4mm) aluminum tube and placed accordingly. This
applies to top and bottom supports only in the upper deck area (Fig. 6).
A. Room is 5’ (152.4cm) and under, two vertical supports are needed spaced evenly.
B. More than 5’ (152.4cm) up to 7’ (213.4cm), three supports are needed spaced evenly.
C. More than 7’ (213.4cm) up to 9’ (274.32cm), four supports are needed spaced evenly and so on.
D. Vertical supports need to be .040" (1mm) minimum gauge.
