I was planning on installing my fresh tank just ahead of the tandem axle and my gray tank just aft of axles like Uwe did on his 63 Overlander. The part that has me baffled is what to do for the black tank. The original toilet had a 3" drain just outside the street side frame rail since the toilet was located in the aft corner of the trailer. While I'm sure that I could install a 4" deep black tank under floor between the frame rails (aft of the gray tank), I'm not sure how to get 3" lines to it. The frame was notched to get the shower drain to the main dump valve, but I'm not sure there's room to run a couple of 3" lines and the gray tank line through the notched frame opening. I really value all the experience of you forum regulars, so any suggestions or ideas on how I should proceed with the holding tanks would REALLY be appreciated! Thanks - Eric
You can use an above floor black tank, like I did, and run the plumbing in a similar way.
I kept the original location of toilet, bath and galley. So far I am very pleased with how everything performs.
You can see the black tank and the plumbing layout in my thread. If you have specific questions, or need detail pictures, I have them ready to go in my i-photo file. Feel free to e-mail me, and i will send info as it is available.
