Moving parts of the entrance door and lock should be adjusted and lubricated at least
once a year or as needed depending on use. Screws and fasteners should be checked and
tightened periodically. Check weather-stripping seals to assure proper fit and seal. Refer
to the Owner's Manual from the door manufacturer for more in-depth instructions for
care and maintenance of the entrance door.
Make sure to check the operation of all exterior lights often. Check headlights,
turn signal, brake, and backup lights to make sure they are working correctly. Remember
to check any towed vehicle or trailer lights also. Replace burned out bulbs as soon as
possible.
The care of fiberglass siding is essentially the same as any automotive finish. Take care to
avoid spraying water directly into any vents when washing the motorhome.
It is important to note that any finish will deteriorate with time. Dulling, fading and
yellowing will be increased by exposure to extreme sunlight, air pollutants, and excessive
moisture. Motorhomes located in warmer weather climates are more prone to this type
of premature fading. Surface weathering of fiberglass does not change the strength of
the fiberglass. Regular washing and waxing of exterior surfaces is the best insurance
against surface deterioration. If deterioration has occurred, check with your dealer for the
steps required to restore the finish. Buffing or even painting may be necessary in extreme
cases. Small cracks known as gel coat crazing are a common characteristic of the gel coat
finish (not warrantable defects).
Wax fiberglass surfaces at least once a year with a standard liquid or nonabrasive paste

wax. Make sure to follow the directions for use as outlined by the product manufacturer.
Make sure to wash and wax your unit out of the hot sun when the exterior surfaces are
cool.
Clean and wax all trim extrusions when waxing the recreational vehicle sidewalls, to
help avoid surface pitting. Special aluminum cleaners are available to restore the original
luster to aluminum surfaces. Make sure to follow the instructions for use as outlined on
the product package.
Storage of the recreational vehicle out of direct sun is also a primary way to help preserve
fiberglass finishes.
Physical damage to fiberglass should be taken care of immediately to avoid moisture from
entering through breaks or cracks, causing problems with interior walls and components.
Cover breaks in the fiberglass with plastic, sealing the edges with tape until the proper
repairs can be made.
DO:
• Wash your RV with liquid detergents.
• Wax the sidewalls using nonabrasive automotive waxes or cleaner/polishes developed
for use on fiberglass boats, showers, and tubs. Follow the directions on the package.
DON'T:
• Use abrasive cleaners.
• Use rubbing compounds.
• Dry wipe surface; clean only with water and liquid detergent.
Proper engine servicing and record of servicing may be mandatory
to ensure chassis warranty protection. Follow the manufacturer's
instructions on periodic maintenance checks.
