Gray water holding tank problem

I have a 2000 3670 RL. I have had trouble with my gray water tank leaking near the front of the unit. I can't see anything with out removing the belly liner. I drain the gray water tank and the leak quits. My sensor units inside the trailer do not work.
Questions... Where does water overflow when the gray water tank is full? Is it possible I have a hole in my gray water tank or is it more likely there is a connection that could be leaking bad? It seems like we have not used very much water after draining when the lead starts. If I have to get at my gray water tank, what is the easiest way to do so? Thanks so much for any ideas.

You did not say if you have had this unit since it is a 2000 model or if you just got it. When the grey water tank is full it should come up in at the lowest part in your trailer, probably the shower drain. One trailer I had the bathroom sink would quit draining when the grey tank was getting close to full. There is not an overflow, just vent pipes that go up through the trailer roof. I would suspect a leak somewhere in the drain piping. All of the RV's I've had are configured this way.

There is also a vent on or near the top of the tank. That could be cracked or perhaps there's a crack in the side or top of the tank. As Charlie said, it should back up into probably the shower.
