I have a 2004 DMAX Crew Cab Short Box Which is awesome. When I was detailing it last night I noticed the bottle jack, but could not find the wrenches and other stuff that go with it. I looked in the owners manual and it is pictured under the back seat. I know Chevy has tucked them in side panels in the past, but am I missing something or did the stealer forget to put it in?

Flip your back seat down. Between the seat back and the back wall of the cab are some flaps. Lift them and look under it. Easiest access is from the passanger side. Had to find mine when I blew out a tire on my trailer. Of course sitting on the side of the road in the middle of nowhere. Fun part was trying to figure out how to get the bottle jack back in. Took me a while to figure out how to re-attach the chocks.
