Is that tank flush below and above the frame? Any idea on how many gallons?
It isn't flush with both, i'm going to get it as close to the floor of the bed as possible and see how far it hangs down below the frame. When I get it mounted tomorrow i'll take some better shots of where it ends up and how it sits in relation to the rails. I did a rough measurement and i believe it's approx. 19 gallons.
