Grey tank issues leaking or cracked?

We had a full grey water tank for the bath. Sitting outside the vent was dripping underneath the trailer. Dumped the tank all was well. So come the next question is the tank cracked or the pipe connection broken. Anyone ever had this issue?

You said Bath? was it cold out that day? could it have been condensation on the outside of the tank because of the warm water inside the tank ?

It is cold but there was too much water for condensation. We are still camping tonight. I will let you know what happens later.

I had that issue on a Berkshire. It started at Goshen thank goodness and FR replaced the gray tank. The reason it cracked was as it became full the top of the tank would expand and as that moved with expansion the PVC pipe the drained into the top of the tank was plumbed without any flex. So the tank would rise up on the top but the connection was ridged and caused the tank to crack at the inlet. They tried to fix it several times but every time it would just be worse. On new units the use a flex hose in the line to allow for movement.
Now this may not be what happened to yours but it's worth checking out.

Funny thing is we had a wicked smell last night in Goshen that I thought was the air admittance valve. Tomorrow morning going to pull things apart and have a look.

On my shakedown trip last year my galley gray tank leaked. The connection at the tank wasn't glued at the factory.
The dealer pulled the underbelly material, washed it and glued the connection. No problems since.

Today I found that the connection to the tank is not glued. The pipe moves around. Now two thoughts. If UT floats the connection won't be broken I'd the tank overfill. It does leak a little once and while I can just deal with that. It is a picture of a inspection camera. The pipe does move up and down on what appears to be a through sleeve attached to the tank. I can get at it by pulling the converter I I choose to seal it up.
This was not the cause of the smell I had in Goshen. That was the air admittance valve.
