We used these in our sloped driveway and turn them over when on level ground. They are 2X8X16" long with a cross-piece nailed to 1 end. The main reason is on some soil they do increase the surface and reduce sinking.

A little off topic - If you look close between the wheels, you can see these are a piece of 6"X6" about 18" long cut in a trapezoid shape. There is one on each side. With a 2X4 nailed to the top I can insert/remove them both from one side which makes it convenient for blocking the wheels.
