Its a lock. I am going to install a gray tank...I have surfed, read and researched until my eyes are bloodshot and my fingers are tired.
I would like to add a gray tank to my 1970 27' rear bath International. What is the largest size I can install? Girls like lots of water
... It says in my manual that I have a 50 gallon fresh water tank and shouldnt my gray tank be able to take that volume of water?
Should I install right before the black tank or should I install it up closer to the axles for weight distribution?? I havent opened the floor anywhere except in the rear so Im not sure what type room I have.
Also, Is it possible to flush the gray water thru the black tank? I realize that I may need to get a new black tank because if I cut a hole in the existing black tank to attach the gray I have an area for a potential leak.
Thanks to all for your information
