Thanks for that suggestion Bill. The other idea I've had is going to a reclamation site to see if I can get a few paving slabs. W.C.; not sure whether your question was directed to me or another poster, but anyway, my solid jockey wheel pulls up onto the outside of the A frame, so a pneumatic tyre shouldn't cause any problems with retraction. I had one on my previous caravan, an Elddis, and it was a dream manaeuvring it about on mixed surfaces. I see the pneumatic wheel assemblies are over £62, so I may have to follow the other options first!
