Deluxe Chock and Lock Twin-Pack is a great product
Among the best and most inexpensive items on the market is the Deluxe Chock and Lock Twin-Pack from Ultra-Fab Products. The two items, which can be found at Camping World, can be placed between wheels and gets the entire vehicle level before a person knows it.
Those who have purchased the item find that it does the job well and is able to handle even the biggest trailers with ease.
"Once you take the time to adjust the chock, it is very simple to use whenever you wish." wrote a reviewer on CampingWorld.com. "Simply place between the wheels and lock the handle into place, it puts a lot of force on each wheel and really stabilizes your camper."
