I bough a motorized Caravan Mover to make my life a bit easier when it comes to maneuvering my caravan around my property. The area where I park my van cannot be accessed by a car to pull it out, the turn is too severe.
My YouTube video review for the Gen 2 Mini Mover 550W 12V above.
The Gen2 is meant to be used on hard surfaces, it does not perform well on wet grass or slippery surfaces.
The manual claims it can pull a 2722 kg caravan up a 7 degree slope, however, I haven't tried that myself.
The Gen2 Mini Mover uses a 12 volt battery for its power source.
I also purchased extra battery clamps for the wires.
Overall the mini mover seems to work quite OK, and I'm happy with my purchase.
The Gen 2 Mini Mover is available from the Ebay link below.
