mystery water leak, where are my tanks?

[gingercamper]

I am restoring my new to me 1984 Bigfoot B17 and there is a water leak I cannot seem to find where its coming from. Slow drip coming out on the kitchen side, under the frame. Its completely dry inside, checked all around the plumbing, hot water heater/plumbing.. nothing. I suspect it could be a seal or small crack in a water tank coming from under the floor? I cannot seam to find any information where the grey water tank is. any thoughts or helpful suggestions?

Might it be condensate from the 'Fridge?

The grey water tank is underneath just behind the axle. It can take abuse back there and either damage the tank ar put undue stress on the drain fitting. I replaced ours including new plumbing, and new sewer gate valves for grey and black water. Try and accumulate some water to confirm if it is gray water.
