If you are looking for an electric or hydraulic system, this would probably be a leveling system and not so much a stabilizing system, if you are just trying to eliminate the movement when someone is walking around or getting in and out, the scissor type that you find on travel trailers work just fine, that is what i mounted on the back of our Class C.
If you want a leveling system HWH and Bigfoot both come to mind, these will level your camper for you.
Hope that helps.
