Is it possible to make the driver side rear outrigger a water tank also?

gotta love line-x

Thanks. We do a lot of water washing up here and have done it that way for so long our customer would probably   freak out if we started leaving huge piles everywhere.

The drivers side outrigger is coated for feul(if at all) and schwing does not approve it for water. They are not the same coatings and any failure do to water storage(rust) will be your liability. I would hate to see that happen.
