Hi, you might like to go into "search" and put "motorised jockey wheel" my post should come up from May 17 2014. On that search list I also just saw another post " optitec remote controlled jockey wheel" for sale. Don't know if it's sold or not??? Yell out if you cant find the posts.
I must apologise to Revemike if they see this. I'm so sorry I never got back to video the action. Plain old forgot!!!!
We still love this jockey wheel. In fact I kissed it the other day!! It saves so much stress for us trying it fit the van into the carport that is only just high enough to fit the aircon if it's in pretty much in the exactly correct spot. Our needs are different than yours. We are able to back our van over the gutter, over the grass on the car. Only have to manouver it into the carport. Without really knowing I don't THINK it would be good on grass, but for our purpose, LOVE it.
Where I am in Townsville as we speak a neighbour has/had one and I was asking him earlier after seeing your question about it. He said it doesn't like the same kerb you mentioned or the grass, especially when wet. He sold it and is looking for a better option. He has a 16ft pop top van.
Good luck with your searching and outcome.
