Black tank replacement for 2004 FR Cardinal

[uscgvet]

My black tank on my 2004 FR Cardinal 32ft fifth wheel has developed a large crack. The FR repair contact person advises that trying to fix it is not advisable. I'm searching for a replacement tank and having no luck. Advice sought.

Can you access the bottom of the tank? If so, there should be a label branded into the tank that has the numbers you need to replace the tank.

Tank-Depot and Plastic Mart both sell replacement holding tanks as well as many others.
