This weekend, I tried to tow the van onto one of those heavy-duty black Milenco levellers, as the (grass) site was uneven.  I pulled it onto the first level ok, stopped the car, put the van brake on, unhitched it - and the van slipped off the block.  Arrgh!
 It did this a few times until I gave up and made do with a wonky van!

Any tips on successfully using these blocks?  I'd have thought it would be easy!
