Hello everyone!
I delivered the 2 x 4's yesterday.
I have stacked them, in a (hopefully) safe manner, so nobody needs to walk on them, in the space between the containers and the tent. I have organized them to largely separate the "shorter" ones (over 6' under 10') together and on top of the longer ones (10' to 12'). These all come from open-framed shipping crates, so there are still some screws / nails in them I could not remove.
Hope these are of use.
