There's a recent thread about these levelers.

If you decide that they are "easier to use" and buy them. I'd urge you to use extreme caution when putting the chock part under the tire. You'll be on a "curved piece of plastic with your tire elevated and subject to rolling. Any distraction could cause you to get your fingers under the tire/Anderson leveler with disasterous results. Also remember that once your RV is "rolled back" onto this and the chock portion is installed, you're going to have the full weight of the RV on the chock, so you'll have to hitch, put your tow vehicle in reverse and "back up onto the leveler" in order to pull the chock portion out from under the tire. That's another potential to have your hand in the wrong place
Just use extreme caution and don't let your kids help with this task !!!!!
