You only need 2 X-Chocks. You don't have to wiggle the trailer around to get them tight. They can't be accidentally kicked out of place, or sink down into soft ground. They don't get muddy from being on the ground. They are lighter than chunks of wood, and work better than curved plastic chocks.
And not suitable for actually "chocking" the trailer, ergo the reason the manufacturer includes a note in every box of X-Chocks warning against using them as a "parking brake". X-Chocks are designed to reduce suspension wiggle when walking around inside the camper,
not to chock it. Any yes, any in-between tire chock can easily fall out of position if they're set in place while the tires are still hot, then cool as they sit.
