Have a 27’ Airstream trailer and have had bad experiences with plastic wheel chocks that fit under the dual wheels.

Are there better wheel chocks that are recommended?

In looking online there are some that expand between the tires/wheels. Are those better? If so which brand is best?

Any and all suggestions and tips are appreciated.

While driving commercial vehicles my employer mandated the use of chocks on very stop whereby the operator had to leave the driver's seat.

We used these, and I still do. Four of them, two on each side of the RV.
