YOLIR MOTOR HOME
Your motor home was designed primarily for recreational use
and short term occupancy. If you intend to occupy the motor
home for an extended period, you should understand that the
additional wear will cause premature deterioration of struc-
ture, interior finishes, fabrics, carpeting, drapes, appliances
and fixtures. You should also be prepared to properly manage
and control condensation and the humid conditions that may
be encountered. The relatively small volume, and tight, com-
pact construction of modern recreational vehicles mean that
normal living activities of even a few occupants will lead to
rapid saturation of the air, and the appearance of visible
moisture, especially in cold weather.
Just as moisture collects on the outside of a glass of cold
water during humid weather, moisture can condense on the
inside surfaces of your motor home during use in cold
weather when humidity of the interior air is high. Water
vapor will condense on the inside of the windows and walls
as moisture, or in cold weather as frost or ice. It may also
condense out of sight within the walls or the ceiling where it
will manifest itself as stained panels. Appearance of these
conditions indicates a condensation problem. When you rec-
ognize the signs of excessive moisture and condensation, you
should take action to minimize their effects.
You can reduce or eliminate interior condensation during
cold weather by taking the following steps:
»
Ventilate with outside air.
Partially open one or more roof
vents
and one or more win·
dows to provide controlled cross flow circulation of outside air
into the interior. While this ventilation will increase furnace
heating load, it will greatly reduce, or eliminate, condensation.
Even when it is raining or snowing, outside air will be far drier
than interior air and will effectively reduce condensation.
