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 (Figure 14-6). 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.
This is discussed further in the “Interior Care of Your RV” section. If you have any questions about
moisture-related issues in the environment you plan to use the RV in for a majority of the time, contact
Tiffin Motorhomes’ Service Department at (256) 356-0261.
