The problem is that there is not a real good place to put cup holders in
the front of a Vanagon, especially if you have roll up windows. they can
be put on the seat base, but they a a pain to use, if you are on the
roll.
I found the solution (for Me) yesterday.
I  purchased a Wolf console, that has 4 beverage holders, storage for my
tapes,sunglasses,change,and other misc. sundries. I know it blocks the
passageway
to the rear, but I almost never walk to the rear that way anyhow.
The Vanagon suffers from not having enough room to store garbage,( up
front,) that is required to function while driving,
and I thnk I solved the problem.
It looks good too!
