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.
Actually, what really happens is that there is a LOT of flex in the elec. stab. jack components - the main downward legs, the pair of angled fore/aft braces on each leg, the bolt assembly that holds the main leg and braces together and the horizontal channel that spans both I-beams. If you want to see what happens, have someone walk up and down the entry steps while you watch the stab. jack assembly. These "stabilizer" jacks simply have too much fore/aft, lateral and vertical movement. One of these days I might take a video to demonstrate what happens.
brulaz on this forum has re-inforced his Lippert stab. jacks with good success. I am planning to do it eventually too.
Some will say that a stacker jack at each of the 4 four corners of the frame will help a lot. They will help with vertical movement, but you will still experience lateral motion. I bought a set of 4 aluminum stacking jacks but they only extend up to 17" max. Our frame is 24" off the ground so I'd need some kind of blocks to make up the difference (more bulk and weight to carry around :(). Another thing about stacking jacks is that the top of them moves laterally a lot. Using these jacks (or bottle jacks) along with the Lock-arm braces (or equiv.) will be as good as you can get. A set of jack just ahead of the axles can help too. Wheel chocks like the BAL X-chocks control fore/aft movement well.
I can see the aluminum stacker jacks being a PITA to set up every time. I'd need something like 4 pieces (min) of 6x6, 12" long or more at each jack. I'd have to store 16 pieces of the blocks somewhere and then I'd have to pull them out when setting up and then have to put them all back when breaking camp. And if the ground is uneven and/or rocky, that could make it even more of a PITA. Not sure if these are going to work for us...
There are a number of the stabilizer braces on the market - Ultra-Fab elminator, JT's Strongarm, BAL Lock-arm, Steadyfast and maybe one or two more. All similar. It looks like the Steadyfast are a bit more cumbersome? I bought the Bal ones because they're available in a two-pack. With a pair of good X-chocks, I don't think you need braces in a for/aft direction. I will try two BAL braces at the rear only and then see if I need some up front.
