Thread: Defender 130 water tank under rear seat box update

With a bladder, if you can get the air bubble out of the top there is no sloshing at all. Don't know if this would be feasible with a bladder enclosed under the seat.

I also have a custom Atlas tank under the rear ... I use mine for diesel, but I wouldn't recommend it for that purpose. I've found it hard to get a leak free seal at the fittings, and the tank has deformed a bit (doesn't really like the diesel) ... still holds though.
