I have the exact same problem. The ones that seem to have complaints are the style that have the single motor stabilizing system where both legs come down at the same time and self adjust. The problem is the systems slides side to side under the trailer to accomplish the self leveling leg process. Unfortunately trailer also moves side to side on this same carriage once the trailer is supported. I plan to do the exact same thing you are doing this spring. I have a set of the Bal Loc-Arm stabilizers in the garage ready to install. Just have to wait until April when the trailer is back from storage. I installed these stabilizers on my old trailer with manual jacks and they made a significant difference. I believe(hope)they will work with the electric ones also and keep the trailer from moving on the jacks carriage.
