So I purchased a 1974 airstream sovereign
31'. Very straight trailer through and through, and I knew the blackwater tank was out of it due to a crack. The PPO (previous previous owner) had replumbed it so waste goes straight out the blackwater pumpout at the tail when I flush... so I can camp IF I have full hookups.
I have the tank... the crack is about 7 inches... and was patched once with epoxy or something... and appeared to crack again. Should I avoid trying to fix the crack and just replace the tank?
Anyone have the schematics on how I replace this tank? I'm ready to tank on this project... I just need a little guidance.
