Nice truck, but watch out. You need to have some kind of a block on that bed when your sticking your head in there, you don't want it coming down on you. those things have been know to blow seals & hoses which makes then drop vary fast, we don't want to loss any of our truck friends this way.

Most of these will have a metal bar that swings down to brace against the frame, some have a stop bar that is not connected to the truck, those get lost, so if you don't have one, use a 4x4 of good quaity, a 2x4 will snap quickly adding to a problem.
