<snip> And I'm adding new BAL stabilizers that'll hopefully reduce or eliminate trailer rock when we're set up.
It also seems prudent to do some reenforcement work on my (2005 Scamp 5th wheel) trailer axle mounts.
Peter, when I had a 2005 Scamp
Deluxe 19' 5vr , like you I tried multiple things to reduce 'trailer rock'.
Spent quite a bit of time trying to determine just what was allowing it to occur. I extended the OEM rear stabilizers to reach the ground, so they were solid. Always chocked in front and behind the wheels and of course the front landing jacks had quite a bit of weight
on them so they seemed solid. Still the rocking was evident from the axle
forward, becoming more noticeable the further forward you were.
One thing that made a significant difference was to stabilize the hitch. Noting that on a conventional 5<sup>th</sup> wheel trailer you can purchase a two or three leg king pin stabilizer, I created one for my Scamp
5vr. That stabilizer made a significant improvement in reducing the rocking motion – perhaps by 70 percent. Eventually I determined that the remaining rocking was the result of landing gear flex. While they were stout and could support a large weight
load, they allowed movement, both side-to-side movement and front-to-rear.
While at home, I placed a couple of floor jacks to stabilize the front part of the frame and they, in addition to the home made stabilizer and rear stabilizers, made the 5vr feel as if it had been given a solid concrete foundation. Amazing what 7 jack/stabilizers will accomplish! Never duplicated that setup on the road, as when using the home made stabilizer the remaining level of rocking was acceptable.
Maybe this will give you additional insight toward a full solution to your 'rocking' experience.

P.S. Did you have a problem with your axle
breaking loose from it's mount?
