ABSTRACT:
A vehicle levelling and stabilizing system for campers, trailers and the like, which is easily attachable to existing vehicles. The system is comprised of a plurality of horizontal folding jacks which can be attached at strategic locations to a trailer. Each jack has an electrically operated gear motor for extending and retracting the leg of the jack. The gear motor assembly is attached to the jack by a motor mount configured to permit the gear motor to be secured at a variety of angles to adapt the system to most trailers. The motors are driven by a switching system which allows selection of one or more of the jacks to produce levelling of the trailer. A suitable level is provided either on the tongue of the trailer or at a convenient location. As an alternative, an automatic levelling system may be provided in which a pendulum system operates the jacks successively until the trailer is level.
