Using a Stable Lift on a truck camper

I have a 94 Skyline Weekender 850. I bought it used and it came with a stable-Lift. I did alot of research and decided It was the best lift for me. Also I saw one and talked to the owner on how he liked it. He said he would not owner anything else. With the camper on the ground the owner pushed on the side then the back of the camper with absolutely no movement. I camp a lot by myself and it is supper easy to take on and off. I did call the company for literature on the unit and they were very helpful. Hope this helps.
