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.
