I have a 1965
Overlander and the Blackwater tank needs to be replaced. I haven't seen this type of tank on VTS or Airstream Supply. I am looking for suggestions for alternate tank options and additional vendors to check for the right tank.
The shape of the tank is generally rectangular (23.25 x 49.5), with one long side having kind of a cut out shape or alcove that begins 18.5 from each short side, angling back from that long side to a segment 9 in length.
Having bought the trailer from previous owners who did alot of plumbing and wiring experiments which we are slowly repairing, I don't even know if this is the original tank. If not. what was the original tank and who carries it? or makes it?
Thanks so much!
