There are plenty of good wheel stabilizing systems for tandem axle trailers but is there anything better than the old single wedge chocks for single axle trailers?
We use rubber wheel chocks in front of, and behind both wheels. They hold well on pavement, gravel, or sand. The chocks are held against the tires by bungee cords\.
I throw a long bungee behind the wheel/tire including the chokes and hook it on the outside. It is an elastic type bungee, not a rubber truckers bungee. I don't need a lot of force pushing the chokes to keep them in place.
