I use 12 ton jack stands.
Two reasons. They have a wider footprint and are taller not requiring cribbing under the stands.
The wood cribbing as tall as required I would be concerned with lateral and longitudinal stability.
I would leave a 5th wheel hitched to the truck to help with lateral and longitudinal stability.
Well with the 12" long 2X4 cribbing, didn't move when I put a shoulder to the back of the 5er and pushed hard. I will trust the cribbing anytime. Like the OP stated in a reply, a bunch of cheap 2X4's once used you can burn in the fire pit. :)
In addition, as mentioned in my first reply, that section of the driveway is not level, I simply shimmed the first layers of cribbing to make the stacks vertical.
