devoted to ensure the slide outs are functioning properly. Each time a slide out is used,
it should be inspected to ensure proper operation and sealing. The slide out gaskets
should also be inspected to ensure proper sealing when the slide out is operated.
During those periods when the motorhome is not in use, care must be taken to ensure
moisture sources are addressed. Ideal storage of the motorhome would be in an
enclosed climate controlled environment. When this is not possible, the following steps
should be taken to ensure moisture is controlled:
• Turn off all water sources.
• Turn off all combustion appliances.
• Drain all holding tanks.
• Drain the water heater.
• Open all closets, cabinet doors and drawers.
• Close all windows and entrance doors.
• Open a vent enough to allow for some limited ventilation air
flow, but not so far as to allow snow or rain to enter.
• When storing the motorhome high humidity climates (ambient
relative humidity is greater than 60% year round), add a
dehumidifier drained to the exterior to control humidity inside
the recreational vehicle during storage.
Areas that are exposed to water spills or leaks should be dried as soon as possible
and definitely within 24-48 hours. Drying areas quickly minimizes the chance for
moisture damage and possible mold growth, which can begin to form colonies in 48
hours. A variety of methods can be used to help the drying process:
• Remove excess water with an extraction vacuum.
• Use a dehumidifier to air drying.
• Use portable fans to move air across the surface.
• Because moisture is key to mold issues, treat all signs of
condensation and spills seriously and deal with promptly.
Failure to deal with a moisture issue promptly may cause more
severe issues where none initially existed, or may make a small
problem much worse.
• Learn to recognize signs of mold - don’t paint over or cover up
suspicious discoloration until you are sure it is not mold. The
affected surface must first be cleaned and dried; residual
staining may be painted.
• Be sure to understand and eliminate the source of moisture
accumulation as a part of the clean-up.
• Small amounts of mold should be cleaned as soon as it
appears. Small areas of mold should be cleaned using a
detergent/soapy solution or an appropriate household cleaner.
Gloves should be worn during cleaning. The cleaned area
should then be thoroughly dried. Dispose of any sponges or
rags used to clean mold.
