Help with stabilizing trailer

I have the same Lippert electric stabilizer jacks on my Starcraft. What a disappointment compared to the manual scissor jacks on my old trailer. What I found is that the self leveling feature of the Lippert system allows the trailer to tilt side to side as people move around. The jacks support the trailer, but the trailer moves side to side on the jack carriage. I installed a set of Bal Lock Arms to try to brace the jacks across the rear of the trailer, but it didn't help much. I had better success adding a set of scissor jacks just forward of the trailers wheels. As they would stick out when cranked up I made them removable when towing. I just slide them into the bracket and crank them down when setting up. Very easy. I used these to accomplish this. Save a Jack
