Water tank for Vanagon Weekender

Looking for a water tank for my Vanagon Weekender that mounts under the van, any ideas?

Check at a place that sells RV’s.

Try http://www.gowesty.com/ They sell all kinds of parts for Vangon’s particularly for campers/weekenders. It would be my first stop. Rv Place or a Vw parts specialist might also sell them.

I dunno, but here’s one that might work. Instructions not included so hope you know what you are doing. Personally I’d just get the round RV type and put it inside a cabinet but you really need to be careful with carrying and storing a potable water supply. I never trusted ours and only used it for washing and not drinking.
