That's the other aspect of it - 4WD vs 2WD. I bought the 4WD Trailblazer when I lived in Chicagoland. Now I'm in SE Tenn, where snow is a rarity.
The only time I'd *really* need 4WD is at the boat ramp... with the pontoon boat, I've got to back w-a-y into the water - up to the bumper on the Trailblazer. When the water is down for the winter like it is now, I can see that at the end of the cement part of the ramp, there's a drop off, if the boat trailer wheels ever went off the ramp it would be a devil of a time getting it back up without 4WD. The cement part can get pretty slimy in the summer time too.
