I have a 2013 Road Warrior 415RW. Twice this summer when I raised the front end of the RV up water started pouring into the generator area. Apparently there was water sitting in the area above the king pin. I can't figure out how it's getting in there. I don't see any moisture inside anywhere. I've checked the front closet and the bedroom and don't see anything. I've been on the roof and don't see anywhere it might be leaking. Any thoughts?
