After a two week dry camping trip, I noticed water running down the outside of the fresh water drain hose. It appears to be coming from where the hose attaches to the tank. I have not pulled the coroplast down to confirm. My RV tech, who owns a Bighorn, says he had the same problem and found the 90* elbow between the hose and the tank became deformed. Apparently it protrudes through a hole in a cross member and is subjected to stress as you travel down the highway with water in the tank. Anyone else have this problem? It's going to be a week or more before the tech can check it out, so I'm just curious.
