Aftermarket auto-leveling jacks

I had the HWH semi-automatic levelers installed on my 'C' at the same place I bought them, Holman Motors in Batavia, OH. Mine are kick down because I'm too close to the ground for straight acting jacks. Long time ago, so I don't remember what I paid. But when you pull into a campground when its wet or raining outside, they're worth every penny. Mine extend in pairs, and all I have to do is push the button that's lit up on the cockpit display. When that light goes out, you follow the same procedure with the next button that lights up. When they all go out, I'm done.
