Best stabilization upgrade(s)?

We are working through the same issue. Too much movement in a longer travel trailer. Thanks for the suggestions so far - looks like I have a few more things to try.

Here is what we have tested so far.

Hush Pad under jack stand. It's a nice thick pad. But it didn't decrease motion significantly.

Stabilizer jack pads. These are nice. Provide some protection for the scissor jacks from the ground. But they didn't decrease motion significantly.

New chocks. Ours were old. Trying a new set. They are plastic but don't interlock with the leveling blocks. Motion increased as it is hard to secure these on the side where blocks are in place.

Super Grip Chock. These are placed between the wheels similar to an X Chock. This did reduce some of the motion and we are happy with the improvement. As others have mentioned, we use these in conjunction with regular chocks.

Your wasting a lot of money and time.

Instead of buying bunches of gimmicks, try a cheap set of car jacks (hydraulic or scissor) located near the center point of your trailer as a test. For testing purposes, you do not need matching jacks, you can use what you have. Once you put jacks under the center point, you want to adjust them tight enough to take some of the downward movement when walking or moving around in the trailer. You do not need to lift the trailer off the wheels.

If this helps, buy a couple of low cost $20 auto scissor jacks for the center support. You want to use the screw type scissor jacks, not hydraulic since hydraulic jacks often will creep down over time.

31 feet is a lot of space to not have "supported" by something solid and what is happening is the tires and springs are, well springing as they were designed.

In essence the frame is flexing or bending and that sends waves of movement all through the trailer. Tires and springs are not solid, they are designed to flex and the longer the trailer you have the more flex you will get unless you put something solid in place to reduce the weight on the tires and springs.

To reduce (you cannot fully eliminate) the flex you must have something solid between the other end supports.

Instead of having 30 ft between the stabilizers you cut that to 15 ft, now you only have 15ft of span that can flex or bounce which will reduce bounce and movement to a tolerable level.
