I have a 25', 1992 Airstream Trailer with a smell we think is from mold. The smell seems to come from below the sink area in the kitchen and bathroom. The smell is worse when it is damp. Any suggestions for this problem or how to eliminate mold and the smell. Also we have a parrot that travels with us so any suggestion should be "parrot safe" Thanks for your help. LCP
You need to find the leak, it could be the floor rotting below. Check rotten floor repair threads here to see what to do. If the smell is diredctly from the drains...clean your grey water tank. Use bleach and water solution, or a commercial tank cleaner.
Look under the kitchen sink and you may see a vacuum vented stack that assist the flow from the drain. The vent is easily removed and replaced with one from Lowes or a hardware store. When you mount the new vent, to ensure that to odour from your holding tank doesn't permeate, make sure that the threads are either covered with teflon tape or they have been liberally smeared with Vaseline (I used Vaseline on mine).
You could have just a plain old blocked vent stack if you have one, (leaves, pine needles, dead bird/squirrel etc. etc.) as well. If you see actual mold, remove with baking soda and water, bleach does not actually do much for mold.
But... it could be your floor from a leak or critter pee from stowaways.

Experience is what you get from not having it when you needed it.
