I have had my truck for 4 months and have made three other attempts to build a mini but didn't work out.  This time it will happen hell or high water.  I took a standard cab bed and shortened it 8 3/4" to fit the extended cab frame.  I welded the fenders and door handles, and also made my own tailgate handle relocator.  I started with the body before I bag it because I wanted it to be clean and smooth before it's date with asphalt.  This spring early summer it should be on the ground.
