An RV seat lift is engineered for durability and ease of use and doesn't require modification of the RV doorway. The unit is professionally installed on the interior of the RV next to the entrance. The user sits on the lift chair, depresses the hand-held control button, rises gently on the vertical lift, and swings the chair through the door opening into the interior of the RV. The double-hinged design allows the custom chair to turn to any angle for easy departure and entrance. If the RV does not have an automatic floor extension that covers the step well area, it is necessary us to fabricate a step well cover for proper access. When traveling, the chair and swing arm assembly is easily removed, and internally stored.
