I bought x-chocks (actually a pair of yellow, Camco 'Wheel Stop' - much cheaper) primarily because my standard chocks didn't grip the leveling boards I use. My other chocks would sometimes slide on the boards making them virtually useless and creating a potentially dangerous situation - thinking the trailer was secure and have it move unexpectedly
An added bonus, the Camco Wheel Stops eliminated virtually all of front-to-rear movement so reduced that portion of the trailer movement.
This is the first time I've heard that leveling and disconnecting should be done before
installing the x-chocks/Wheel Stops.
So... my leveling procedure has been...
Level TT from side-to-side using boards.
Install Wheel Stops on both sides.
Disconnect from TV.
Level TT from front-to-rear.
Lower TT stabilizers.
I could, if necessary, try releasing then re-tightening the Wheel Stops to remove any tension. I'd rather not do that due to the risk of having the trailer shift.
