FWIW, I've got a CBI rear with a swingout. However, I bought mine used so I can only chime in on certain aspects.
1) I was definitely floored when I first saw the costs of them with a TC. I was expecting it to possibly be in the $1500 range, but phew! I was in a discussion about them during one of my trips and was informed that the hinge itself was the major cost factor. So you may want to look into that if you're going the R&D route.
2) I had mine picked up, so I cannot confirm about shipping costs. I do however know that I got my SW front cost ~150 (I think? Don't remember anymore) to ship to VA, and that was splitting the freight cost with 2 others. BE SURE YOU KNOW WHAT'S INCLUDED IN YOUR DELIVERY COSTS!!! They wanted to charge us an additional $100 in "lift gate fees" to just take the damn things off the truck and put them on the curb. I guess it was foolish to think that curbside delivery included them dropping the damn thing off on the curb.
3) I don't really have any beef with the appearance of the bumper (I've also got an 06 bumper on an 03, which has a VERY MINOR fit difference in the fender flares), but my biggest problem is that they don't afford you any additional ground clearance. Tack on the additional weight, and you've actually got a loss of clearance. I installed the bumper very shortly after I got a set of DR's on, so I couldn't give you an accurate loss, but I figure it'd be almost an inch if you were still riding stock.
4) Could the thing be lighter? Sure. But I'll tell you what, I bounced my ass end hard coming down a rock this past weekend and there wasn't a single ding on the bumper. There was a scrape on the underside mounting bracket, but damnit if that didn't make every extra pound worth it IMO.
5) The damn thing shakes like a som***** when I get to about 65mph. It's from the vehicle shaking as a whole, but it still gets annoying because sometime you'll hear the squeak of the TC. I don't think there's much I can do about that though...
6) The kind I have has the screw on latch, and for some reason now that I've added the steel cable to keep it attached to the bumper, it's gotten unscrewed a 3/4 after a bumpy ride and will clang like no tomorrow until you go back there and tighten it. Doesn't do it on paved or even gravel roads, just when off roading. I'm debating on installing a lever latch, but this one is still functional, so I haven't figured out what I want to do with it yet.
Well, that sounds like alot of negatie at the end, but it's really been great from my experiences. I don't like the loss of mpg by turning my truck into a tank, but hey...you gotta make sacrifices I guess.
