over on the IG16 forum they are talking about the Uniko levelling ramps/blocks.

Quite a nice design, english site with pics here:

Not strong enough to be used as bridging ladder, but could be used as sand mat etc

And, yes, i know we all have other methods for levelling the van, but this gizmo is worth a look.
