Calculations for Holding tanks

[Brian Diehl]

I too built my Water tanks.  Craig gave me a free training session on welding one day and then I proceeded to design and build my own tanks.  I didn't create as much capacity as others have, but am very happy with what I ended up with.  I put my fresh tank under my bed (~105 gallons) and my waste tank was built to take advantage of the space in the bay (~115 gallons).  You can see details here : http://home.earthlink.net/~diehls0792/BusSection6.html

I have read where a large tank might need a partition within the tank so it won't shift weight as much going around curves.  Maybe this should be a consideration.

Come on guys tell Danny about your Baffles  .

Ok

I have two baffles in my 165 gal fresh water tank and one baffle in my hundred gallon grey water tank and no baffles in the 65 gallon black water tank.

I that what you meant??

Okay, my waste tank has 3 baffles running across the tank (short distance) and one additional stiffener baffle on the high end of the tank that connects the outer wall with the inner baffle to help prevent any bulging out on the high end.

My fresh tank has 3 baffles running across the tank (narrow dimension).

I built plywood/fiberglass holding tanks about 20 years ago and they worked well all the time we used the coach.  Now, after sitting idle for several years there is some seapage.

I was thinking  about using spray in bed liner to repair these tanks or build new ones.

Any thoughts or experience with the stuff.  It sure is tough in the back of a pick up truck.

I'm still trying to figure out where and how to install mine in my tanks.....
I'm really baffled.
