We have a 1996 Grand Teton San Diego II 38-foot fifth wheel. There is a musty odor that is very elusive that we can smell occasionally at the front door and in the kitchen area. There are no signs of water damage anywhere. We've taken out all the kitchen drawers and looked under the counter and its dry. We've inspected the backs of the cupboards and they are dry. We've run the A/C and heater and did not smell anything.We had the roof re-sealed a couple years ago. Any ideas?

I found mine under the bench of the dinette. I had some stuff stored in the cabinet and pulled it out to find the rug wet.

Thanks for the input. We don't have a bench but a table and chairs across from the kitchen. There isn't any evidence of dampness there.

Well, if you smell it, then you have it. Look for sagging material under the 5er. Push on all of the wood you can underneath to feel for softness. If it ever did leak up top, eventually the water found its way to the bottom and stayed there. The kitchen area usually has holes to allow plumbing into the underbelly.It's possible you have enough moisture to have mold but it hasn't been long enough to really feel the soft wood. Keep looking, hopefully you will find the problem area.

Did they hide the water pump under one of the kitchen drawers? They do leak sometimes.

We don't use the water pump because our rig is permanently parked in an RV park. However...good point. I'll check this.

Shower/tub drain under the pan...???
Hopefully not. They are really hard to get to.

You might get better answers if this was posted in the Fifth Wheel forum instead of Class A. You have nooks, crannies and places to look that we might not know about...just sayin.....Dennis.

We had a small leak under the sink that filled up a pan with a dish towel in it. The towel became moldy and caused the smell. When we opened the cabinet couldn't see any evidence of water or mold. It wasn't until we pulled out the pans that we discovered the pan/wet towel.

Had to replace the faucet to fix the leak.
