ABSTRACT:
A motor home has a rear, extensible room portion that does not require ground support. The extensible room portion comprises a rear wall, roof portion, and a pair of sidewalls having integral top extensions extending over 40% forwardly of the extensible room portion and serving as lever arms. The end of each lever arm has rollers which roll on upper tracks below the roof of the vehicle while the side wall portions roll on tracks at the base of the sidewalls, either of which work in conjunction with fulcrum rollers in shifting and distributing its weight while extending or retracting the extensible unit, whereby the overhanging extensible room portion can be partially extended to a balance point, and will exactly balance, whereby the overhanging weight of the rear portion of the extensible room portion when moved outwardly of the balance point will be resisted solely by the resistance of the tracks on which the upper rollers roll so as to distribute the overhanging weight along two upper tracks and greatly facilitate extending or retracting movements of the extensible room portion.
