I've spent a lot of time looking for a front winch bumper and rear bumper with backup sensors set for my '13 Z71. The best quality I could find is Fab Fours
http://www.fabfours.com/ Their Premium set, with a Warn Zeon 12 (12,000#) winch is going to run me about $6500 installed with the PreRunner guard. Buckstop also appears to be a well made product but they don't make rear bumpers for our SUV.
The answer I got on why few manufacturers make serious bumpers for Tahoes and Yukons was that most people don't seriously off-road $60K to $80K vehicles. I find that interesting since people off-road $100K+ Hummers and Rovers. Guess they only expect soccer moms to drive our SUV's. I regularly run pipeline ROW's and industrial project property before anyone else ever sets foot on it. Ditches, streams, and gullies are not atypical and the BS cheesy bumper covers my Z71 came with will rip off the first time I encounter anything more serious than a twig.
As far as "looks" go, if you want pretty, stay off the dirt. Pretty is in the eye of the beholder. Coming home at night safely is my version of "pretty" vs being stuck where there are 8 foot rattlers, feral hogs, coyotes, gun totting drug runners (I wear Danner Snake Boots and carry an M4 and 1911 personally in these areas), and all other kinds of nasty's foraging or looking for easy prey. Yuck made me hit the floor LMFAO. I love the street but my Z71 is for off-road use.
