Setup & leveling

Chock the wheels before you unhitch, every time

Stabilizer jacks and leveling systems are not built to stop a trailer from rolling. The only thing between a parked Airstream and the campsite below it is the wheel chocks, so they go in before the truck comes off.

1. Chock on the downhill side first Set a chock snug against the front of the front tire and the back of the rear tire on the low side, so the trailer cannot creep in either direction.
2. Let the trailer settle onto the chocks With the chocks in, put the truck in neutral and ease off the brake for a second so the trailer rolls the last fraction of an inch into them. Back in park, parking brake set.
3. Add X-chocks between tandem axles On a dual-axle trailer, a scissor-style X-chock clamps between the two tires on each side and kills the rock that works a single chock loose. Snug them by hand, do not overtighten.
4. Now unhitch and level front to back Only after the trailer is locked down do you drop the jack, disconnect, and run the tongue jack to level. Use industrial rubber chocks, not the thin plastic wedges. They grip on gravel and grass where the cheap ones skate.
