The advantage of manual stabs is you can crank them a little tighter and take a little more movement out of the RV. But it isn't night and day, its more like noon and afternoon.
I finally added the SteadyFast system to ours. The difference is night and day. Its still not as sold as a block house on a cement foundation, but it is so much better.
