ROUTINE MAINTENANCE
Use exhaust fans, the air conditioner, and/or a portable dehumidifier to manage moisture inside the RV
to maintain relative humidity at 60% or less. In cold climates, relative humidity may need to be at 35% or
less to avoid window condensation issues. If the motorhome is used the majority of the time in a hot,
humid climate, it may be difficult to keep relative humidity below 60%. A dehumidifier will help, but is
important to check the condensation (water) collection bucket regularly or discharge the condensation
(water) directly to a drain.
Avoid drastic thermostat setbacks
To minimize the opportunity for condensation to form on interior surfaces, maintain a comfortable
temperature in your RV, and avoid nighttime setbacks of 10 degrees or more. Drastic setbacks that
reduce the indoor air temperature quickly can increase the chance for airborne moisture to condense on
cool surfaces such as windows. If you are away from your RV for an extended number of days, it is
recommended that you do not set the temperature back without taking other measures to manage
relative humidity, including operating a dehumidifier with a continuous drain.
Manage Window Condensation
Window condensation issues can be identified by water or ice-build up, usually at the base of the
window. The majority of these problems can be addressed by managing moisture generated inside the
motorhome. Minor condensation issues are not unusual, especially for RVs used in colder climates. To
help minimize window condensation, use exhaust fans vented to the outside, avoid drastic changes in
thermostat settings, do not use "vent-free" heaters and use window coverings wisely. For example,
make sure to open curtains or blinds during the day to allow air to circulate and warm the window
surface.
Carpet Care and Moisture Management
The carpet should be cleaned when it shows signs of discoloration or traffic patterns. A steam cleaning
system should be used to clean the carpet unless other noted in your warranty information. To manage
moisture from the cleaning process, the cleaning system needs to be capable of extracting the excess
water from the carpet after it has been cleaned. Important: Be sure the carpet is thoroughly dry before
closing up the RV for storage. Water from the cleaning process can cause significant damage to the RV if
the carpet is not completely dry before closing up the motorhome for an extended period.
Cleaning Tile
Most floors only require a mild detergent and warm water for cleaning. More water on the floor is not
always better for cleaning. Use a damp cloth to clean on a regular basis rather than wet mopping each
time.
Storage and Other Isolated Areas within the RV
Storage areas are more difficult to condition since the areas are isolated from the main body of the RV.
The surfaces of these areas are more at risk for condensation and surface mold growth. To minimize this
risk, clean storage areas regularly, and allow an air space between stored items and the exterior wall to
promote air circulation.
