Hi, I have used a powered jockey wheel. It was on a far larger van, but I couldn't get on with it. The area I needed to move the van into was quite tight and with the power on the mover it rocked and jolted the caravan whenever I stopped and started it. Did the job but not smooth. The other thing to bear in mind is its weight on the nose, or if you need to change the jockey wheel, it would not be easy. Would recommend motor mover which fits under the caravan, Very easy to use and does the job very well. Hope this helps. Have fun
