Abstract: An automotive vehicle has a transmission through which an engine can deliver torque to an axle to propel the vehicle and a transfer case associated with the transmission for operating auxiliary equipment. A system for engaging and disengaging the axle from the transmission and for engaging and disengaging the auxiliary equipment contains a first solenoid (20) that operates to a first state when the vehicle is to be propelled and to a second state when the auxiliary equipment is to be operated and a second solenoid (22) that is selectively operable to a first state that causes the auxiliary equipment to be disengaged from the transmission and to a second state that causes the auxiliary equipment to be engaged with the transmission through the transfer case.

Abstract: A support system for the interior of a mobile vehicle such as a tractor-traileror over the road heavy truck. The support system provides vertical support poles for use with various features of the truck vehicle. The poles are integrated into the structure of the sleeper. They provide additional structural rigidity and limit the roof crush in the event of vehicle roll-over. The poles are equipped with various external accessories. They may have a swivel seat attached for additional seating within the sleeper. Sound system speakers may be hung from the poles and aimed where desired. A television or computer monitor may also be hung off the poles enabling adjustment for numerous viewing angles within the cab and the sleeper. The poles may also serve as a conduit for heating, ventilation, and air conditioning for the sleeper environment. The poles can serve as the air ducts or a separate duct could be installed within each pole to channel air to multiple air outlets.
