We added the Winfield Stabilizers to our 5th wheel this weekend.
All I can say is WOW!
They do exactly what there are advertised to do.
To eleminiate the shakes we had tried BAL X-Chocks on both sides of the rig.
A tripod, and home made stabilizers from Harbor Freight.
Nothing really worked until we added the Winfield stabilizers.
SWMBO noticed right away. Shaking is about 90% eliminated.
The magic combo for us was the X-Chocks and the Windfield.
Scott was real good to work with and his product is top notch.
Just though I would share our experience.
