I built this tailgate bench for my Z-71. I find it easier and faster to set up than my bench rest and it works OK. The extra length gives room for a free standing Magnetospeed chrono.

1/2" plywood is light enough, yet strong and stiff enough with 2x2 bracing. The extension is to get out of the way of the tailgate cable.

So, my range is where I park the truck...
