A caravan mover is a caravan manoeuvring system consisting of two or four electric motors driving rollers that engage with the caravan tyres to move the caravan. They can move the caravan in any direction, forward, backwards, turn and even rotate on the spot (single axle vans). All this is controlled by a simple remote control. The drive rollers are engaged with the tyres to manoeuvre the caravan and disengaged when you are towing, they are powered from your caravan leisure battery.
