Leak in underbelly, possibly grey tank?

My wife noticed water dripping from the underbelly of our 2015 DRV mobile suites 39dbrs3 yesterday. The dripping was in line with the door, but as I found this morning was running down the belly from a couple feet farther forward. I checked the kantleak and didn't see any signs of leaks and the tanks looked dry as well. I could feel dampness in the bottom of the insulation but the top is dry. I then noticed the tank was showing full and when I ran water in one master bath sink sink the other gurgled. I drained the tank and gave it a light flush of about 20 gallons. Now at the end of the day the drip is gone and there's no more sign of a leak. Wondering if the gray tank might have been the cause. I've attached a pic showing the area where the insulation was wet, near the bottom of the drain pipe, and one of the belly.

Water can run a long ways, as it will always seek the lowest point. I had a similar drip once, and the leak turned out to be 15 ft from the drip.
My only advice would be to check all the connections on drain pipes and water lines, as they are a lot more likely to leak than a tank. Hopefully the source is a minor fix, and not a tank. Good luck.

You sure the water isn’t coming from the over flow on the fresh water tank. Even on city water my valve was still letting water into the tank over flowing it. New valve no more leak.

I'm starting to think it might be the washer. My wife was draining the tanks yesterday and noticed water around the storage compartment under the half bath, which is where the washer and dryer are. I need to figure out how to remove this compartment to get a look
