Dummy here again FWC closed so ask here. I'm at state park with water & elec. Reached 32 and windy. Went to explore and came back... water dripping under truck. Thought maybe just drip at intake fitting. Checked good... wife went in camper and water on floor. Something is leaking... I had drained freshwater before trip so is empty. I am guessing maybe water line from input? Should I try using onboard water by putting some in tank? Is there something I can or should check... nothing can be seen leaking inside where water pump is. I have 2015 Hawk with side dinette if that helps.
