A few years ago we got a CoachLift for our MH. It is basically a removeable chair that hangs on a double hinged bracket fastened to a screw post to lift from ground to MH floor level that then swings into the MH for the convenience of the passenger. We use ours to lift our special needs teens from their wheelchairs to the MH, from which we transfer them to the inside seats. The post is mounted near the door and can be inside or outside depending on your MH configuration. During travel, the chair and bracket are removed for storage. We would not be able to travel without it.
Google Coachlift. They have several models of lifts and provide excellent customer service.
We recently traded MH's and with the exception of the bottom post bracket, the whole thing readily transferred to the new rig. The bottom bracket had to be slightly reconfigured to the frame requirements of the new MH.
