Definitely some sort of military truck, probably FMTV made by Oshkosh.  Some of the numbering is Hebrew.

And there’s a bunch of them, up there

squeezing under

the Bayonne Bridge, as they and the rest of the cargo

aboard the Norddeusche ship

rounds Bergen Point on the way to Port.

All photos by Will Van Dorp, who has seen military trucks and other vehicles atop the boxes previously here, here, here, and here.   Once I even spotted a cigarette boat way up there.
