I used Camco light weight yellow chocks on our 30ft trailer. They worked fine, but when I tried hitting one with a hammer it cracked and snapped, so I settled on these black rubber pads. They are slightly stronger and work well. They have a bit more weight and I like that they have a metal grommet on them so you can attach a rope if you want to pull them out or tie them together as a set.
