Grey tank 1 and 2 on a Dutchman Coleman Toyhauler 250qt

Question

Over the weekend, I noticed the bathroom sink was plugged. Grey tank 2 said it was full. I did not realize this RV had 2 grey tanks. Something Camping World failed to tell me. I looked under the RV all over from front to back and both sides and did NOT find a grey tank dump except for the one that is hooked up with the black water. Please help? I have no idea how to drain that other tank?&nbsp;

You didn't say if you have already, so...did you try draining your findable gray tank and the black tank and see if that helps? It's certainly worth a shot.
