The present invention relates to an adjustable control system for a caravan moving system in which the caravan movers each include a brushed motor. The adjustable control system can control two caravan movers (10) mounted on a single axle caravan or two caravan movers mounted on a twin axle caravan or four caravan movers mounted on a twin axle caravan (quad system). The caravan moving system comprises a control unit, a user operated actuating device, power means and a drive unit. The present invention utilises a control system which provides variable movement of the or each caravan mover (10) and also provides gradual changes in both speed of each brushed motor and the subsequent ability to smoothly change the direction of travel of the caravan. In particular, the present invention enables the caravan to follow a wavy or curved line of travel in which the radius of the turn varies (i.e. from 0 degrees to a spin on the spot (equivalent to a 90 degree turn)). Accordingly, the caravan can follow sinusoidal and/or elliptical lines of travel without intermittent stops to provide sequential directional changes. Furthermore, the user has the continuous ability to simultaneously vary the speed.
