I have 2 lengths of timber, one 3/4 inch thick the other 1 & 1/2inches thick, and just wide enough for the tyre (about 6 inches)and just long enough for both wheels and chamfered at one end to form a ramp. I just check how far the van needs levelling with a spirit level and put the appropriate ramp in front of the tyre and pull the van onto it. In some instances I have used both, one on top of the other. No problems at all. I store them under the fixed bed via the side access locker.
