The new Mover XT scores a first by using a brushless DC motor. This extremely efficient high-tech motors allow significant weight savings and the improved efficiency means it can be operated on a much smaller battery.  Being 5kg lighter that its predecessor the SE R and needing only a 38Ah battery means more space and more loading options for your caravan.  The Truma Dynamic Mover Technology® allows extremely precise directional stability. This is achieved by clever electronics that monitor the motors and ensure they always move at the correct speed. The effect is that the caravan moves straight ahead like it's on rails and it easily overcomes any obstacles without drifting from side to side.  See More Info.
