In an old TT I was rebuilding, I needed the black tank due to a fracture around the neck at the toilet attachment point.
Old trailer, no parts available.
I went to my local RV service / parts store. People there were always helpful and great to deal with.
They had a catalog of generic tanks, made by some aftermarket company. I removed my old tank, took some careful measurements of the exact size, location of toilet flange, vent pipe and drain along with the desired sizes of all that and took this info to them.
They handed me the catalog to browse and I found a tank that was close to the same size. I gave them the diagram of where the holes needed to be and ordered the tank.
They took a generic off the shelf size tank and custom made it for my application. When it came back, it fit perfectly.
And it didn't break the bank to order. Don't remember what I paid for it but it was quite reasonable.
