My blazer was fine in the snow, so long as you took it slow and steady.
A few years back during a snow storm that closed down rt17 here in Jersey, I drove up to Ramapo college and "rescued" my ex from there, as she woulda been stuck there over the weekend.
All the cars were pulled over or bunched up plodding along barely, but I just kept on truckin.
we got a good foot and a half over the night. Don't get me wrong, I wasn't driving 50+ on 17 by myself. Nice steady 30 got me there, and kept me toasty with the engine heat..
.. god I miss that truck so.
