A rollcage is always a great safety addition no matter what type of wheeling you do. We wanted to keep as much interior room as possible in our '00 GMC extended cab, so we gutted everything from the headliner down to tuck as much of the 0.120-wall, 13/4-inch DOM tubing out of the way. Creating a precision fit is no simple task. To get the bends right, Mel Wade from Off Road Evolution created a tube template that allowed him to adjust the bars to the right length and sweep. Then using it as a guide, he built each section accordingly.
