70 • Section 3 — Exterior & Interior Care Cayman 2006
EXTERIOR MAINTENANCE
The motorhome is subject to a great deal of outside conditions. When parked, the motorhome is exposed
to extreme temperatures, humidity, ultraviolet rays, rain and other organic environmental conditions. While in
operation the motorhome is subject to twisting and fl exing caused by rough roads, potholes and winding mountain
roads. Maintenance is necessary to keep the exterior looking nice and to keep in proper working order.
Fiberglass
Inspect the fi berglass exterior. Periodic inspection may reveal that fl exing of the fi berglass exterior has
created imperfections in the surface commonly known as spider or hairline cracks. A crack that has opened up to
reveal the weave of the cloth threatens the integrity of the fi berglass. Prevent moisture penetration if the exterior
exhibits signs of damage, particularly in freezing climates. Cover the area using plastic sheeting or tape, and have
the damaged fi berglass repaired as soon as possible.
Roof Care & Seal Inspections
Periodic resealing of the joints and seams is necessary to prevent the entrance of moisture into the motorhome.
Enough emphasis cannot be placed on this issue. Extreme damage from a water leak can occur rapidly. Never
leave the motorhome unattended with the slide room extended. If the motorhome is to be stored outside
throughout the winter months, a full interior inspection for water leaks should be made twice monthly.
Extensive sealing has been done at the factory; however, the normal twisting and fl exing that occurs while
traveling may have compromised a seal or seam.
CAUTION:
The roof surface is slick in all conditions. Exercise extreme caution when accessing the roof.
INSPECT:
All joints and seams should be inspected at least twice a year and recalked as necessary.
Special attention should be directed toward the roof air conditioning seals, ceiling and plumbing vents,
skylights, roof mounted antennas, windows, door molding, clearance lights and the beltline molding.
Specifi c sealant products should be used in the areas for which they were designed. These items can be
obtained from recreational vehicle parts suppliers. Listed below are some of the more common sealants and the
areas in which they are used. Approved sealants are available at service centers and authorized dealers.
WARNING:
Some products may contain hazardous materials which require special handling. Read
labels carefully. Follow all of the product manufacturer’s safety requirements.
