Our custom seat lift operates powered by a 12 Volt DC motor with hydraulic actuator . 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. The carrier arm/articulating hinge can be lowered into the step well for travel.
