looks very nice, though I'd prefer to weld it to the frame. I dont have a front hitch, but my crossmember is welded. The whole bumper and crossmember tightened up my front end noticeably.
Your handy work is much nicer than mine. Just to me it seems four bolts fitting two not machined together surfaces will allow a decent amount of flex. That crossmember is the only area tying the entire front of the truck together.
