Long Term
Long term storage of the motorhome can be defined as leaving a motorhome unattended for a peri-
od of thirty days or more. A motorhome requires protection from the elements just as a house or a car
would. When left out in the environment without proper storage or maintenance, a motorhome, house or
car is vulnerable to the moisture and oxidation processes inherent in the environment.
NOTE:
The natural process of moisture in the air condensing will occur with temperature
changes of 30º F or more in one day. Humidity readings of 60% or greater will
allow the accumulated moisture to remain for extended periods of time.
If the motorhome is stored in a location where AC power is not available:
• Turn off all the appliances.
• Turn off the battery cut-off switch.
• If possible, situate the motorhome so the batteries remain accessible. This allows a battery to
be charged or replaced without moving the motorhome.
• Charge the batteries to a full state of charge.
• Turn the main battery disconnects OFF.
• When stored outside, make a quick reference check of the battery voltage on the moni-
tor panel. Preventative measures should be used if the voltage readings are low.
Removing the motorhome from storage or moving the motorhome in case of an emergency
will be a much easier process.
NOTE:
Batteries in a low state of charge will readily freeze. Freezing will damage the bat-
tery.
CAUTION:
A 20 Amp service using light duty extension cords and the required adapters create
serious voltage losses. Line voltage loss and the resistance at each electrical connec-
tion is a hazardous combination and should be avoided. Damage to sensitive elec-
tronic equipment may result!
Type of surface to park and store the motorhome on:
• Parking the motorhome on a grass surface, with the tires supported by blocks, is a perfect
situation for moisture to accumulate.
• A graveled parking area still allows moisture to evaporate from the ground, through the
gravel and to the underside of the motorhome.
• Concrete pads seal the surface allowing better ventilation under the motorhome.
• Storage buildings with concrete floors, or heated storage facilities, greatly reduce the
amount of moisture accumulation and protects the motorhome from moisture damage.
If the motorhome is stored outdoors:
• The interior should be heated to help prevent mold and mildew growth. Moisture removing
desiccate filter systems are available from hardware and RV supply stores. Place the filter
system inside the motorhome to reduce interior moisture condensation or humidity.
