Thanks for the feedback. Yes the tubing is gray so I will look into that. I believe the leak is coming from the faucet underneath the vanity. I hope I can get into fix it. These bathrooms are small and I am not.
Will work on it this weekend. We have Camping World and other places with RV parts in town. Not sure we have a HiLo dealer anymore. I knew of one like 20+ years ago but I was a kid then. Never thought I would own one. My dad and I used to look at RV's a lot. I remember going to the HiLo dealer with him and looking at trailers. I asked him if we would ever get one. He told me not to get my hopes up. He's glad that I have one. He has a 1976 Sportscoach motorhome. It is too short for me inside standing up and on the beds.
