I hame a Marlin front on my Runner.On New Years eve an 03 Cadillac pulled directly in front of me and took a 40mph hit in the side.My bumper was slightly tweaked only do to the fact that it only had the front 4 mounting bolts in it.The Cadillac is probably in a 24"x24" cube form right about now sitting in the scrap yard.Doesnt get much more heavy duty than that!!
