Wheel chocks make sense with any kind of trailer, or if you have hydraulic brakes utilizing the driveshaft e-brake, and no jacks. In my old gasser class A's, 1 with and 1 without jacks, I used chocks with no jacks but never felt any need for them with the jacks down. When jacks were extended, that thing wasn't going anyplace. Even if the jacks sunk into the ground, it would have taken a bulldozer to move it.
With air e-brake and jacks, the use of chocks doesn't compute at all with me. Would you chock prior to setting the jacks? Seems to me that the coach may need to move a bit and reposition itself as the jacks level things up. If you chock after setting the e-brake and jacks, seems you'd be in a big bind when leaving if you forgot to remove the chocks before retracting the jacks. Nope, makes no sense to me...! YMMV
If you are worried that the coach will shift when up on the jacks, it seems that you already flunked "Camping 101" when choosing that site to set up on.
