Anybody ever thought of doing this. I was sitting on the thrown going through the JC Whitney catalog and was thumbing through the RV section. You can get a 6 gal tank (says 12'' long)for like $40, a small electric pump for $20, and I figure maybe another$20-$30 for wiring and some kind of fixture or small hose. Hmmmm, thinking mounted in back behind the seat against the sheet metal on the side....would take up some space, but wouldn't it be cool to have your own water supply on the trail and when camping for under $100! Something to think about.
