2003 Winnebago Journey DL Seat Lift required only 2.75” of wall space for inside installation. Another bonus is the 12 volt motor and the remote operating system is hidden behind the over head cabinet.
RV Lift’s RV Handicap Seat Lift is powered by a 12 Volt DC motor and operated by a wireless remote system much like the one you use to lock and unlock a car door. Motor operates on 12 volt DC power using a rodless ball screw linear actuator system with a rated force at 200 to 600 lbs. It can be installed on most RVs with minimal modification to the RV. The lift must be supported and firmly attached to a solid member of the RV structure. The top of the lift tube is attached by a bracket through the interior wall of the RV. The swing arm and chair assembly extends into the interior of the RV. The seat can be stored inside the vehicle or in an external cargo bay.
