Fastway's ONESTEP wheel chocks are designed for tandem-axle trailers and RVs, wedging between the two tires to keep the trailer from rocking or rolling once it's parked. They set and release from a standing position, so there's no kneeling down at the wheel well.
Sold as a two-pack, they fit wheels from 16 to 24 inches long and take the place of hunting around the campsite for rocks or blocks to steady the trailer.
A more comfortable, no-kneeling way to stabilize a tandem-axle rig at the campsite.
