I have the electric stabilizer jacks and love them, even though the rear ones quit working. The crank moves them faster than the old manual jacks, anyway. To keep the small amount of movement from happening, I use a thick piece of rubber floor mat under each pad (between the pad and the plastic blocks) and it keeps the little bit of movement from happening. I also have a small bottle screw jack that goes between the wheels, under the spring, and that keeps the swinging/sway of the center frame under control.
Wish I knew how to fix my rear stabilizers. I've checked the wiring, and the fuse. and the switch. Everything seems to be alright, but no worky...
