Section 3 --- Exterior & Interior Care

• Proper winterization of the fresh water system will prevent potential damage in extreme
cold.
• Ultraviolet radiation affects soft goods and rubber products such as privacy curtains, win-
dow shades and tires. These items should be protected. Store Day/Night Shades in the
Up position.
• Cardboard templates can be made for the windows to protect the interior from exposure
to direct sunlight.
• Tire covers are available to protect the sidewall of the tires from cracking. Make sure tires
in storage contain the correct air pressure to prevent damaged caused by underinflation.
• Regularly washing the exterior to help control moss accumulation. Waxing the motorhome
twice a year will augment these substances.
Inspect the motorhome:
• Perform a full interior inspection for water leaks every two weeks while the motorhome is
in storage. Check inside all cabinets for signs of dampness or leaks. Inspect the ceiling
areas around roof vents or other roof openings.
• The roof and sidewall seams should be inspected and cleaned at least twice a year.
Inspect for exterior sealant gaps of all roof seams, vents, skylights, roof air conditioners
and windows.
Fuel:
Storing the motorhome with a full tank of fuel will minimize moisture condensing at the top
of the tank. Diesel fuel is an organic material which will develop a microbe growth (black slime). Fuel
stabilizers may be added to control microbe growth and degrading of the fuel. Consult the engine
manufacturer owner’s manual or a distributor for further detailed information on fuel stabilizers and
additives.
Brakes:
Brakes suffer from non-use during periods of storage. The bare metal machined surfaces of brake
drums or rotors have only a light coating of dust from the brake lining friction material. The brake dust is
the only thing protecting the bare metal surfaces from rusting. Only regular brake applications dry the
moisture preventing rust on brake drum or rotor surfaces. During periods of non-use, oxygen and
moisture oxidize the machined surfaces. Only occasional use keeps these surfaces from oxidizing. Rusty
brake drum or rotor surfaces permeate the brake lining upon the first few applications, reducing the
friction action of the linings.
Engine:
Internal combustion engines need to be “exercised” on a regular basis to ensure an adequate supply
of lubricating oil coats the cylinder walls and piston rings. Valve and valve seat surfaces also suffer
from non-use. Some valves will remain open depending at which part of the combustion cycle the
engine has stopped. The heat and cold of the day allows moisture to accumulate through the exhaust sys-
tem. Start the generator at least once a month.
