Thanks for quick reply…that’s the same one I had located….not the same size to match up to gray tank plumbing. I ended up ordering 2 tanks and will have to replumb both in a different way. Shame that I can’t buy. identical replacement for the TravelStar tanks it came with. But that’s why they call it plumbing …Cheers and Thanks anyway

I had to replace mine in my 2006 Montana. The dealer said they couldn't get an exact replacement, but a similar one that was slightly smaller was used.

Replaced both my black and grey tanks 6 years ago
and just measured them and went to my local independent RV dealership and they ordered them. They are identical except discharge sump is mirrored. I had to cut in all my own fittings by measuring, had the old ones right there. Not a difficult job IMO.

Surplus Online Seats & More had my 2005 Montana Black Tank when i Had to replace it in 2018... They still have tanks online.
Did take a month to get it though and installation was somewhat complicated. Needed a rubber fitting to reconnect the Vent pipe and used a flexible rubber coupling between the Toilet and the tank hard plumping.

Trekwood or Colall RV is where I would try.

Edit: my gray tank had 3 cracks and was leaking when 1/2 full. I was able to repair it with ABS glue & wire screen. Still good after 3 years.

IconDirect.com either has the tank on hand, or can manufacture what you need. Another option is to find a local company that specializes in making tank repairs. The most important feature is the discharge port size and location. The vent hole is cut in by the installer. Forget Trekwood as they are always high priced and will charge handsomely to ship it. Most likely they will be a middle person who finds the item, charges you double then orders the part from the same place you could have bought it from for 1/2 the price.
