Well regardless of Vanagon or Eurovan, I purchased the vehicle cover for a
1986 Vanagon Westy and bought it from Bus Depot about 3 years ago.

I have only used it for one winter and the van is housed in a carport and
so it is already protected mainly from the elements.  The primary reason I
bought the cover was to store my van over the winter, especially once I got
it completely refurbished with body work completed and new paint splashed
on it.  Still not yet completed - but I think maybe by the end of this
summer it will be ready and I'll break out the cover again for the coming
winter months.

Anyway I really like the BD cover - seemingly good thick material and it
has 3 zippered access points to the 2 front doors and the sliding door.
This is really handy ro get into the van and check moisture, turn a space
heater on or off, check the batteries, check for critters, sit in it and
have a cocktail during the winter and pretend you're camping etc..  I think
the Eurovan covers also have the zippered feature and will likely be the
same material.  When not in use - the product rolls up like an extra big
old style sleeping bag - probably the size of 2 cubic feet or so.

I give the Bus Depot product my full endorsement (for a Vanagon Westy) and
for my set up.  If I recall, it is also reasonably priced and I was knocked
out by the speed of BD's shipping from the North East US to Vancouver
Canada.
