Dave;
If you've got the stock tank and sender, half way up is where the sender is mounted to the tank. mine leaked years ago. the sender hole is about 1 1/4 inches around with 6 screw holes. the screw holes had cracks emanating outward past the rubber gasket.
I took the tank out and had the hole welded closed as I installed a new monitor system with the rubber well-nuts.
I’m not sure that welding is still an option on a now 40 year old tank. I had mine welded about a dozen years ago. this past winter I had to replace that tank as it had begun to decompose from the inside out.

Now before you even say it, the obvious answer is that there is a crack halfway up. That may indeed be the case, but I was wondering if anything else
could be the problem?
If I fill the tank full (by the gauge, not until water comes out the vent), it drips very slowly out the back of the coach. If I drain it until the
3/4 light goes out, it can sit forever and not leak a drop. The system holds pressure and the pump does not cycle.
The tank is not easily accessible to inspect (Royale rear bath). Any thoughts?
