Why are you putting your tongue jack blocks in the wrong way?
Should be long ways with slope, not short.

Nope - we've been through this before. :R Look carefully at how I chock the trailer and you'll see it can't go anywhere as forward pressure exerted by the rear set of tires pushes against the rear set of rubber chocks which in turn pushes against the hardwood spacers which in turn pushes against the front set of chocks which in turn pushes against the two front tires. Those wheels are bolted to the wheel hubs which are part of the axle assembly which is bolted to the equalizers which are bolted to the trailer frame. Regardless of slope there is no lateral pressure of any kind on the tongue jack or the stack below it, therefore I can place the stack any way I want to. How 'bout that. ;)

Never totally trust wheel chocks, lateral force WILL be induced if you lose air in a tire.
Lateral force can also be introduced by the board slipping on the driveway the tires rest on.
Therefore you place the blocks correctly.

Nonsense. I did lose air completely last year when one of the curb side tires suddenly deflated while the trailer was sitting on the driveway chocked just like this. The tire was later determined to have split, with a large oval shaped delamination bubble inside the tire. The trailer didn't shift a centimeter and I replaced all four of these original Chinese tires with Goodyear Endurance. Secondly, look carefully and you'll see the 2x wood sitting on 3/4" thick rubber tread, that elevating support isn't going anywhere. I've been chocking and elevating the tongue jack with variations of this same process for 20 yrs now, I have zero concern about the trailer ever shifting. :B
