I guess I should have been a little more clear Brian in my description of the mounting systems. The Ali-Arc mounts are as described-plates welded to the bumper structure itself. The Ute mount is a whole extra subframe behind the bumper itself-basically think of the bumper as a shiny shell covering a bunch of ugly iron

. The bumper bolts to the mounting frame with IIRC 3 large bolts on either side-bear with me-it's been 3 months since I put it on and a lot of water has passed under the bridge since then.....
I don't think you'll find an Ali-Arc that will take a winch-like John said their intent is more towards front-end protection. Doesn't mean they couldn't crank something out for ya if you talked to them though.....
Is either the Ali-Arc or the Ute stronger than the factory bumper? You betcha-especially the Glad-wrapped tin can that passes for a bumper on the Sport trucks

. Is either stronger than the frame? I'm sure they are. Is the Ute stronger than the Ali-Arc? I would wager it is-whether or not it matters is a debatable point.
In my opinion (very important underlining!

) the Ute looks better-and also in my opinion it's stronger. It's not perfect-if I had been starting with a blank piece of paper I would have made it a little wider and made the headlight protection tubes wrap all the way around to protect the front corners. I would also have added a little more in the way of air openings in the front of it. And I would have put in LED lighting in the corners instead of the incandescent stuff-that is 1 area that I plan to address myself.
One of our ABC buddies is building bumpers now-I'll have to dig through the pics I have to see if I got some good ones of his truck. They are cool looking things-winch mount is standard-and he will build either aluminum or steel depending on your preference. No idea on price though.
