Mildew smell

[pvene4664]

in my Class A motorhome Im having an issue with a mildew smell. I have checked every cabinet, the carpet,the canopy, everything I can think of. My front a/c has started dripping from the roof instead of the tube under the rv. Has anyone had this issue with this drainline clogging and how did you solve the issue? also, have any of you had an issue with mold inside your walls?

Take a wet dry vac and suck it out of the drain tube.

When luan gets wet, it bubbles out and we could see the damage under the infused wallpaper. The pull-out table was also damaged and needed repair.

yankeeclipper how did you find it inside the walls

Once you find the source of your smell, fix it and then go rent an ozone generator to remove the smell and kill the mold.

Funny you should ask.
I had water seepage in the front passenger window, as the drain holes had clogged and the water came over the sliding window channel. The water soaked into the luan siding and ran inside the wall as far astern to almost the passenger door. Just yesterday I finished the repair: I scraped away the ruined luan, the sanded the rest to the Styrofoam inner wall. That was where the smell was. I also had to replace two wood stringers that had rotted.
I replaced the luan plywood with Allure vinyl planking (flooring, really) and glued into place. The we shampooed the carpet, and the smell has started to dissipate. It also looks pretty good, or so DW says...
The whole project took about three weeks of intermittent effort to complete. Hint: dried water-damaged luan explodes into sawdust with the use of an orbital plane sander, so put up a dust barrier or expect a major PITA cleaning up the dust (like I did!). HTH
