Grey water tank leak?

I have a 2006 Coachmen Aurora. We were at Myrtle Beach last week and I noticed while wife was in the shower water dripping from my black/grey water dump compartment. The water was not coming from the dump valves but appeared to be dripping on the top side of the basement storage compartment and running down into the dump valve compartment.

Since we've been home I have tried to locate the source of the leak with no luck. I have checked under the shower pan, bone dry, the drains run above the floors and dumps into the grey tank via elbow, all of this is bone dry. The tank is mounted up against the floor no way to check where drain goes into tank.

Has anyone had this problem or have any ideas what may be going on?
I'm at wits end, would appreciate any help.
  • Check for hair line cracks around the tabs where the 4 screws are that hold the blade in.

    Took us forever to figure that one out after I unnecessarily replaced the blade, because the water from the leak around the screws runs down the pipe.

    After we found the hair line crack when we went to loosed the screw the whole corner came off. Found hair line cracks on both black and gray. Mobile repair says he sees it happen all the time. Plastic, stress and the bouncing of the RV while traveling down the road.

    How about leak from hot/cold water fittings on shower faucet and or the faucet

    Good idea to check out. Also try a couple spoon fulls of food coloring mixed with water dumped down the shower drain to verify water supply or drain.
