Yes there are 2 small wheel chocks stored with the bottle jack behind the backseat on passenger side. I would suggest keeping a few pieces of 4x4 or 4x6 to put under the jack, I do not think the jack will reach the frame on its own. I havent tried it, because I am lazy, but by looking at that little bottle jack and how high my stock height truck sits I dont see it happening. Good thing the truck, my auto insurance, and a couple of my credit cards all have free roadside assistance.
Most bottle jacks can unsrew the center of the piston to almost double their effective height.
