ROUTINE MAINTENANCE
Use of Un-Vented Combustion Equipment
Un-vented combustion equipment, such as propane stovetops are a source of moisture within the RV.
For every gallon of fuel consumed, approximately one gallon of water vapor is evaporated into the air.
Whenever possible, operate an exhaust fan in combination with the use of any un-vented combustion
appliance within the RV. Water vapor and other combustion byproducts should be vented to the
exterior of the RV. The RV owner should strictly follow use and maintenance instructions for safe
operation of any combustion equipment, particularly un-vented equipment.
Exterior Care of Your RV
The exterior shell of the RV is the primary weather and moisture barrier. Over the life of the vehicle, the
shell will require regular care and maintenance in accordance with other instructions for exterior care.
The shell includes the roof, sidewalls, windows, doors, and under-floor of the vehicle. Particular
attention needs to be devoted to ensure these components are maintained to ensure a tight barrier
against bulk water intrusion. The shell should be inspected periodically for tears, gaps, and condition of
sealants in accordance with this owner's manual. Areas that require maintenance should be resealed
utilizing a similar, high quality sealant used by the manufacturer. Particular attention should be 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.
Use of Your RV
It is important to remember that the square footage of an RV is significantly less than that of a single
family residence. This fact alone will elevate the relative humidity because there is less volume of air to
help absorb or dissipate the humidity. For example, showering and cooking create a lot of humidity in a
small area. In these instances, use of an exhaust fan and opening windows should reduce the relative
humidity, particularly when living in the RV for an extended period.
Severe Environments
Prolonged use of your RV in severe environments—for example in extremely cold or hot-humid climates,
will require extra care and maintenance to avoid moisture-related issues. In both extremely cold and hot
humid climates more attention needs to be focused on controlling relative humidity within the RV. It
also may require the use of a portable dehumidifier to manage relativity humidity within an acceptable
range.
Storage of Your RV
During those periods when your motorhome is not in use, care must be taken to ensure moisture
sources are addressed. Ideal storage of your RV would be in an enclosed climate controlled
environment. When this is not possible, the following steps should be taken to ensure moisture is
controlled:
