When we picked up our trailer 12 years ago, our friends who had a similar one suggested we get a ratchet jockey wheel to help move it around. We ended up buying a Manutec EM1 and it is still going strong. I couldn't imagine having a camper without a ratchet jockey wheel as they are so useful. Great for pushing the trailer into tight spots, moving it to line up the Treg hitch, or pushing it back into the garage. Simple to use, strong, and as it is permanently hanging off the side of the trailer, robust. I just looked up the price of the current ones and was a bit stunned, but then thought we have had 12 years use of it so far.
The only issue I have had with it is that the 'handle' sometimes comes off the wheel while manoeuvring the trailer, frustrating but I can live with it.
