PREPARATION FOR TRAVEL
If the rooms cannot be retracted according to the
ROOM RETRACT Section, retract the rooms according
to the MANUAL ROOM RETRACTION Section.
The system should then be checked.
The room systems or generator slide should be cycled
once a month or whenever the vehicle is used, to keep
the system in operating condition.
Maintain adequate clearance in all directions for vehicle, room
extensions, awnings, doors, steps, etc. Vehicle may move in
any direction due to jacks extending or retracting, settling of
the jacks or the vehicle, equipment malfunction, etc..
