So I have to park my Panda on our driveway now. when i reverse it up the driveway our hitch is quite close to the ground. This means the jockey wheel is attached with the 2 clamping rings of the outer barrel above the clamp. I have to extend the jockey wheel to full extension to get the rig close to level but I'm concerned about long term effects of doing so. The driveway at the front of the van is on too much of a slope for using a standard jack. How else can i support the weight whilst I move the jockey wheel barrel further down the clamp? I don't trust the stabilizers to take the full weight and 1 is already slightly bent from a previous owner obviously trying to something similar.
