For possible varied Vanagon and shop use.   I may have mentioned this
before, if so sorry for the doubly- redundant redundancy..

  Look at horse stable mats as a possible source for floor covering or
engine deck area mats in your vanagon.  I have them on some of my benches in
the shop and as cushioning where I work.  They're made from reclaimed
tires.  Come in various thicknesses and are really durable.  I have front
floor mats cut from them in my van and one for outside under my slider in
rough camping spots,  My wife has them in her barn and stable stalls.  They
would also work as sand traction mats for the Syncro crowd.
