Seals and Sealants
The exterior shell of the motorhome is the primary weather and
moisture barrier. Over the life of the motorhome, the shell will
require regular care and maintenance. The shell includes the roof,
sidewalls, windows, doors, and under carriage of the motorhome.
Regular inspections and maintenance is required to ensure the
exterior shell provides a barrier against water intrusion.
The shell should be inspected periodically for the condition of
seals and sealants. Check corner and joint moldings for sealant
damage. Areas that require maintenance should be resealed
utilizing a high quality sealant that has the same or similar
characteristics as the original sealant.
Check door, window, and vent seals for cracks, chips or other
damage and replace damaged seals as soon as possible. Extra
care needs to be given to all roof-related seals to prevent water
intrusion from the roof:
• Air conditioner seal or gasket
• Roof racks
• Fans and vents
• All mounting points and wire ports
NOTE: Damage caused by lack of sealant mainten-
ance is not covered under the Thor Motor Coach
Limited Warranty.
Extended Stay Usage
Your motorhome was designed primarily for recreational
use and short-term occupancy. If you expect to occupy the
motorhome for an extended period of time, be prepared to
actively address condensation and the humid conditions that
may be encountered.
The relatively small living space of an RV contributes to an
environment where normal activities of even a few occupants
can lead to rapid moisture saturation of the interior air.
During cold weather, when relative humidity of the interior
air is high, moisture condensation on surfaces can become
significant. Estimates indicate that a family of four can
vaporize up to three gallons of water daily through breathing,
cooking, bathing, and washing.
Unless water vapor is carried outside by ventilation, or reduced
by a dehumidifier (customer supplied), it will condense on the
inside of the windows and walls of the motorhome. Moisture
may also condense out-of-sight, within the walls or ceiling
panels, where it can cause warping or staining. Appearance
of these symptoms may indicate a serious condensation prob-
lem. Always take necessary action to minimize the effects of
excessive moisture and condensation.
Cold Weather Usage
When using your motorhome in freezing and below freezing
temperatures, these precautions should be taken:
• Make proper preparations to avoid freeze damage to the
fresh water and waste water systems.
• Propane regulator freeze-ups can occur in any weather if
there is moisture in the tank or if the tank has been over-
filled. Always use moisture-free propane fuel and make
sure the tank is not filled beyond 80% of capacity.
• During cool weather usage, ventilation or the use of a
dehumidifier (customer supplied) may be required to
reduce condensation.
• To avoid damage due to cold weather, check the exterior
for frozen moisture before operating or using the motor-
home’s doors, locks, windows, and vents.
NOTE: Thor Motor Coach’s Limited Warranties do
not cover damage caused by the use of your motor-
home in freezing temperatures.
Maintenance Access Panels
There may be maintenance access panels located in key
areas of your motorhome. Access panels allow service and
Your motorhome is not designed, nor intended, for
permanent housing. Use of your motorhome for long
term or permanent occupancy may lead to premature
deterioration of its structure, interior finishes, fabrics,
carpeting, window treatments, etc.
Damage and/or deterioration due to long term occupancy
is not considered normal and may, under the terms of
the warranty, constitute misuse, abuse, or neglect, and
therefore void certain warranty protections.
