leveling...
I have a couple of leveling blocks that I made from plywood and 2"x6"s. I used sheetrock screws to sandwich the 2x6s between the 3/8" plywood, cut an angle on one end and screwed in a screendoor handle on the other.
I store them on my rear rack and lock them on with a cable thru the handles....keeps them from disappearing and holds them in place while bouncing around. I never need more than the two blocks...under the front, rear or side tires. In the cab I have an aftermarket leveling instrument from a jeep, however something hanging from the rear view mirror seems to work as well....when it is hanging straight down, the rig is level. That along with my wife guiding from outside, we get it pretty right-on. Like Hayduke, we use an icechest so just comfort in bed is the only issue.
