Yes, it did originally come with a jack. I can't really say for sure on an AD truck where it would go, but on the TFs it would go on the left side of the floor, behind the driver's side of the seat toward the cab corner. Mine didn't have a jack with it, seems that that's one part that always missing. Probably the same Gnomes that take the 1 sock out of the wash

. I did find that a Larin 1 ton bottle jack fits nicely in the carrier, though.
