The portable Garage from Costco at about $170 sounds about as close
as you are gonna get to your model-12' x 20', not sure of height, but
close, sides w/ windows w/ flaps, doors at both ends that zip up,
etc.   Many other similar products out there also, but the poles,
cover, etc. might be more than you wanna store in the vanagon, but
anything that large is gonna take up some space & weight.

Volks at Burning man, etc will gang up many of these tents together
for their compounds.

YMMV,
