I'm a relative new owner (last year) of an older truck camper (1994 9.5 Shadow Cruiser) with the Stable-Lift already installed. I can attest to the pros/cons others have commented on. Also, I contacted the manufacturer (Mont Peters) via phone to try and find out more info and how best to install the saddle brackets (what the lower hoop retracts onto) on the truck frame. This guy was amazing; answered all of my questions/offered suggestions, as well as emailing me a copy of installation instructions (very very informative). I didn't need to install the saddle brackets, since I have running boards installed. The system is very stable when loaded in or out of the truck, as well as quick and easy to offload. I'm a very happy owner and haven't encountered any problems with the system.
