Storage of the Motorhome
During periods when your motorhome is not in use, care
must be taken to ensure damage to your motorhome caused
by excessive moisture and other conditions does not occur.
The ideal storage location of your motorhome would be in an
enclosed, climate controlled environment, however, this is
not always possible. Follow these important storage steps to
protect your motorhome:
• Turn OFF and disconnect from all water sources.
• Turn OFF all combustion appliances.
• Winterize your motorhome’s water system.
a. Drain and flush all holding tanks.
b. Drain the water heater tank and fresh water lines.
c. If freezing temperatures are expected, treat plumbing
pipes and fixtures with RV antifreeze.
• Slightly open all closets, cabinet doors, and drawers; this
allows for air circulation.
• Close all windows and entrance doors.
• Open a roof vent enough to allow for some limited venti-
lation, but not so far as to allow snow or rain to enter the
motorhome.
When storing the motorhome in climates of high relative
humidity (greater than 60% year round) control humidity
inside the motorhome by operating a dehumidifier (customer
supplied), drained to the exterior.
Winter Storage
When storing your motorhome for the winter, extended peri-
ods, or in other extreme conditions, certain precautions need to
be made to protect it from possible damage. Make sure to talk
with your local RV dealer concerning any special requirements
for long-term storage in your geographic area. The following
steps are general and your dealer can help you choose those
that are most appropriate to your needs.
CHASSIS:
Perform chassis maintenance and recommend storage
procedures outlined by the chassis manufacturer (oil, filters,
transmission inspection, tires, brakes, etc. Refer to the chassis
manufacturer’s owner’s manual).
TIRES:
Block up motorhome with wooden blocks or on a hard, level
surface to relieve the constant pressure on one area of the
tires. Inflate tires to their maximum pressure. Cover to protect
against sunlight with burlap, plywood or specially designed
tire covers, which are available at RV dealerships.
BATTERY(IES):
• Be sure that both the chassis and auxiliary (coach) batter-
ies have the proper electrolyte level and that they are fully
charged. Add distilled water and recharge if necessary.
(NOTE: batteries installed in your motorhome may be
sealed or maintenance-free).
• Batteries should be checked for charge at least monthly.
Use of a trickle-charger may be appropriate. Inquire
with the battery manufacturer regarding trickle-charging
methods. A discharged battery could freeze and may
crack the case, causing severe damage to the battery and
surrounding area. In storage, a battery will lose charge
gradually over a 30 to 45 day period, even when discon-
nected from the positive and negative battery cables.
• You may wish to remove the batteries from the motor-
home and store them in a heated area (approximately
50° – 60° F). However, even in warm storage, the battery
charge level must still be maintained.
LITHIUM BATTERY POWER SYSTEM:
Refer to the manufacturer’s documentation for long-term
storage and care of the Li-ion battery pack(s) and system.
FUEL:
Store the motorhome with a full fuel tank, treated with
a fuel additive to prevent condensation buildup and fuel
degradation. Use fuel additives recommended by the chassis
manufacturer.
DASH AIR CONDITIONER:
Operate the unit for a short period of time throughout the
storage period to assure the compressor seal is lubricated.
EXTERIOR:
Clean and wax exterior surfaces. Lubricate locks and hinges.
Seal roof joints and mounting points as needed. Follow
exterior cleaning guidelines outlined in the TMC Care and
Maintenance System Guide, available through your on-line
TMC Owners Resource account.
WINDOWS:
Treat seals with silicone spray. Close and lock. Inspect exterior
body seals and reseal if necessary.
