Techincally it's legal if it does what your state requires. Screw DOT approval. Unless you've got a duplicate (or however many the need to trash/test) of whatever you make to submit it for safety testing it won't be DOT approved. DOT approval is an insurance gimmick. Maybe if your reciever failed while towing and (heaven forbid) killed a handful of ppl then you'd be f*cked. Don't worry about it in the least, I've seen the stuff you've made, it's good work. You're good to go bro, get in the shop and get started if you've got the plans all ready. Like I said, all you have to do is meet your state's bumper requirements. I took a pic of Andy's bumper to the local PD and they said "Yeah that's fine", so that gave me the green light on my slightly modified design. I'd recommend doing that if you're concerned about legalities.

I was going to reuse the oem brackets. Once I seen them and compared it to my fab I was like f*ck that. These things are like a joke compared to the bumper I built. My grade 8 bolts would shear(hah) or my frame would crush before my bumper would budge.
