I believe Euro Campers can also order one that's pretty close to
what you're looking for, although Steve doesn't show it on the web site.
The one on the web site is Reimo #61003; I recently finished
installing one on my van.  (It needed a lot of modification, in order
to get around my air conditioner hoses - it's made for vans without
A/C.)  It's well made, and I'm happy with it.

Reimo tank #61002 is designed to fit in the space you described
(or maybe in the similar space on the driver's side, if there were no
propane tank?).  It holds 60 liters, and its dimensions are roughly
1340 mm long x 310 wide x 200 high (roughly because it's irregularly
shaped to fit the space).  Reimo's price is DM 139, vs. DM 119 for the
#61003 (which Steve sells for $95 including shipping).

Reimo sells about 50 different tanks, including 4 specifically for
the Vanagon.  Besides the two already described, there's a 45 liter
one that's about 950 x 320 x 180 mm (#61000), and a roughly cubical
40 liter fresh water tank (#61001).
