Those are the factory sensors back there. Road Armor does not sell bumpers with the holes drilled, but the guy I purchased this set from on ebay had done it so I lucked out. That was the main reason I wasnt going to buy a rear bumper. I hate to lose a feature that the factory gives.
Winch should be here on Friday. I'm going to go with the Recon 17k and see how it works out. I will barely use it (in fact I'm going to have to find reasons to), but the big gaping hole bothers me. And if this craps out at least I didnt spend $1500 on a Warn winch to begin with.
The tires are great. I had put an identical set on my 06 last May (with factory 20's) and they worked out really well. They dont wear too bad, and the noise level is doable. They do get louder after a few thousand miles but I was used to it by that point. My only complaint about mud tires in general is that I have to be religious about rotating them. All in all, though, these are one of the fairest priced set of tires in the size range (mud or AT) that is load range E. I did a lot of research, but it all boiled down to the local shop having a set of these in stock. My other option was the BFG all terrain 325/60/20, but those cost almost $100 more per tire. Very glad I went with these again. Plus they look outstanding.
Thanks for the compliment
