you can build anything you want, it just takes steel. can't remember who, but a couple guys on CC have done it kinda recently. years ago I carved up the bed on my wheeler for more clearance. soon after I regretted it because I found it completely unnecessary, but then I made peace with it because it's a rusty hunk of rust that drops rust every time you touch it. I could easily have fabbed a bumper that offered protection rather than thinking I needed to emulate the serious rock crawlers since I don't drive my truck like that.
