Gravel driveway to store caravan

I propose to get quotes for a gravel driveway for the sole purpose of storing my fairly small van (Lunar Ariva, dimensions 5.18 x 2.03 metres).

However, I am thinking there could be a bit of a problem manoeuvreing the the van on a gravel surface - for instance, if the jockey wheel digs into the gravel whilst being pushed forward by the motor mover.

Does anyone have experienve of a gravel driveway for storing a caravan and if so what has been their experience of manoeuvreing it on this surface?

Various grids (e.g. Marshalls Drivegrid) are available to stabilise a gravel surface. Does anyone have experience of these?
