How do you use levelling blocks with Alko wheel lo

I have only ever stayed on sites that say they are level and therefore I am sure have missed out on some excellent sites. The reason is our caravan has a Alko Wheel lock, I have read the discussion/posts on the merits or otherwise of the Milenco leveller and don't really think I want one of these. The only alternative is some other type of leveller, such as Fiamma, if I am to stay on a site that needs some sort of levelling aid. My query is how do I level my caravan with levelling blocks and still fit my Alko wheel lock. At the moment on level sites I can move the caravan slightly forward or backwards using the motor mover. Will I still be able to do this and level my van? I hope this makes sense to caravaners more wise than I.
