3500 replacement waste holding tank

[winsorii]

Has anyone found a replacement holding tank for a 3500?

Todd Industries has a number of tanks.

I've used these guys to make a custom holding tank for me:

They have a massive selection of pre-made tanks, or you can use their form to create the exact tank you want, including the number, size and location of whatever fittings you want.
