Introduction
The Rhino Box
pin box is utilized on the Space Saver
Upper Deck (Fig.1). This chassis design gives the 5th
Wheel additional floor space and minimizes the large
step commonly seen in front of cabinetry or inside walk-in
closets in today's 5th Wheel.
NOTE: The Extended Rhino Pin Box has been developed
to provide additional clearance on certain tow vehicle
models (please consult with your dealer or contact Lippert
Care Center).
