I've got Duratracs on my F250 and Silent Armors on my wife's 4Runner. I really like both tires and both have performed very well for me (I don't usually see snow, though). The Duratracs are not any noisier than the less aggressive tires that I replaced with them. Not sure on fuel mileage, but it is probably lower (I increased tires size and put a 2" lift on at the same time, so it's hard to tell if anything was changed just by the tread design).
If you move up to 285s on a 17" rim, you can get D rated tires (for the Silent Armors, at least), which may be a good compromise for you regarding weight ratings.
