Howe (our trailer – Home on Wheels) has the wiggles. With proper chocks under the wheels, and the stabilizers down, it still feels wiggly when walking in it. Stabilizers on smaller travel trailers are not levelers. They are designed to stabilize the trailer once it is leveled. Even with Howe leveled and stabilized, you can tell when someone is walking in the trailer. I did in-depth research (watched several YouTube videos) and decided to order X chocks.
These are jack like devices that fit between the tandem wheels of the trailer and pushes against the tires. This will greatly diminish the front and back movement of the trailer. This does not replace wheel chocks. It just enhances the stabilization of the trailer.
I have found these to greatly improve the comfort when inside HOWE. It even stays stable when Charla does the high jump into our bed. (more details in another post). They work great with HOWE but will also work great with fifth wheels.
