I am definitely in snow country (we've already had a foot or two with plenty of wind) and have 3-2wd GMC's. The '72-3/4 ton has taken me through most of the 35 winters I have owned it with a few months with the 1955 GMC and a 1991 Sonoma scattered into the mix the last 6 to 8 years. The Sonoma gets worked when it is near zero or below, but the other two are more fun to drive so they get used whenever possible.
These trucks ain't my toys--they are all I have to drive. My toy is a 1970 K5 4x4, but even when it is back on the road it will probably not see much of the heavily salted roads we have around here.
