As a person traveling alone, they (along with a giant level on the front) made getting level an easy job. Prior to them, I had to get in and out of the truck numerous times trying to stack boards to the right height for how far I thought I might be out of level. With the Andersen levelers, back or pull the trailer to close to where I want to be. A quick glance at the giant level to see which side was low, walk to that side and place the levelers against the tire. Pull up until level said I was good. Set emergency brake and check to see if ball in level was still centered. Walk to side with levelers, insert the chocks, and then start chocking the other tires. Also always chocked opposing sides of the tires with rubber chocks too. I used the big rubber truck type chocks as I didn't trust the plastic ones to stay in place. Once this was done I began the process of unhooking and leveling tongue to bumper.
I always said if carrying them meant I got a site that was level side to side, I was still good. Much easier than worrying about uneven site, I could get the site I wanted. So many sites here in GA state parks have tree roots causing them not to be perfectly level. Levelers made dealing with roots a no stress issue.
