Help! - gash in black tank

[mondotiki]

I bought a used toy hauler trailer and noticed about a month in that the black tank is leaking due to a one and a half to two foot slit across the width of the tank.

Can this be repaired by me or do I need to take it to a service center? Or should the tank be replaced instead of a repair attempted with a gash that long?

We are back to using a port-a-chem toilet in the tub for now. Wife is not happy.

Personally, I would replace it. Call a mobile repair guy if you need to or take it to an RV repair place.
