Looking for Model# for Black water tank

[Dexxy]

I have a 2006 Keystone Montana 5th Wheel, I bought this used so i don't have any manuals etc. Our black water tank is leaking and our repair person asked for the model number but of course I don't know where to look. Any suggestions on a way to look that up?
thanks

They used to write the model number on the outlet end of the tank. Drop the coroplast and take a look.

It probably isn't going to help, but this is the link to the Trekwood page showing the tanks for 2006 Montana's, and the two tanks 24" X 63" X 8" are the black and grey tanks, but when you click on either one, they show NLA, No Longer Available but they do show a model number for each. https://www.trekwood.com/parts-searc...23+%2F+Keyword

Maybe RecPro?
