Freshwater tank question??

[HeaveToo]

Search the forum and you may see where I changed out the Water Tank when I owned Saga.

Do a good search on the internet and you can find a reasonably priced 13.5 gallon tank.  It was not the bow shaped tank but a square shaped flexible tank.

Here is the key...When you replace the tank line the bottom area with closed cell foam.  I bought a big 1/4" sheet of this and I lined the entire area with it.  It protects the tank.  Also secure the tank well so it doesn't move around much.  This way you get a lot more use out of the tank.

While you are in there I would suggest replacing the water lines.  I actually added pressurized water and it was a nice addition.
