We use a combination of Andersen Jack Blocks, Steadyfast Stabilizers, and a BAL kingpin tripod stabilizer. The trailer is now vastly more stabile.
The Jack Blocks allow us to level without extending the jack arms as much. This decreases the lever arm effect so there is less arm to deflect.
The Steadyfast is noticeable more so in the main room. While the rest of the trailer is much more stabile, I could still feel the rocking and rolling in the master bedroom.
The BAL kingpin tripod stabilizer has made a HUGE difference In stabilizing the master bedroom.
I suspect it is because of how much the master overhangs. The tripod stabilizer adds the sorely needed support.
We have triplet 8 yr old boys that run and jump. It no longer feels like we’re inside an old airplane in heavy turbulence.
