Fresh Water Drain Leak

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.

Having the same problem with my 2014 BigHorn (3570rs). Full timing and on the road, will have to make plans soon to have it repaired.
Let us know what the solution is, when you get it fixed.

Here is the fix for the damaged fresh water drain. They placed a piece of 1/2" plywood under the fresh water tank. This gives it added stability and less flex when traveling with water in the tank and raises the drain fitting 1/2" higher. This should prevent the fitting from coming into contact with the frame cross member as it did previously.
Only time will tell, but it seems like it should work. Hopefully, my pictures are attached.
