I built this system to help my wife enter the camper from a wheelchair without using steps. The Lazy Susan is guided inside a frame of a plywood platform, which is raised to the height of the camper entrance (~22"). The Indeelift is sitting on a smaller wooden platform that is bolted to the Lazy Susan. Once she is sitting on the lift from her wheelchair, she can raise the electric lift to the waist height with the push of a button. I will then spin her 90 degrees to face the entrance of the camper door. She will be able to stand up and grab onto the handlebars at the door and everywhere inside.
