My family does exclusive dry camping because we like to get away from the crowds so I depend on on-board water storage. My first TT was a 19' 2004 Fleetwood Pioneer and it had a 50 gal. fresh water tank that was fabulous. With a tank that size we could almost last 3-4 days with no issues. I loved that tank because it was entirely sealed except for the fill tube and the vent tube which was immediately adjacent to the fill tube. This allowed you to fill that puppy all the way to the brim and you wouldn't lose any during travel. We outgrew that trailer and our 25' 2011 MVP Summit only has a 35 gal. fresh water tank but this tank is designed differently. It has the fill and vent tubes like our last one, but if you crawl under the trailer you can see there is a hollow point in the center of the tank and a rubber hose dangles from the top of the tank. If you fill up the tank, water starts leaking out from this rubber tube under the trailer before it will ever come spilling out of the fill point.
Now my issue - We usually fill up our tanks before heading out to the boonies and when we arrive I find that virtually half of my fresh water tank is gone! I believe that this different tank design is allowing a large quantity of water to exit this secondary venting on top of the tank and as the water sloshes around during travel, I lose A LOT. Has anyone had a similar problem and solved it? I never had one issue with my prior TT's tank and it didn't have a secondary venting system like this one seems to have. Can I somehow just seal up that sucker under the trailer and go back to the good ol days?
