I don't know. I have been there before in snow... I have been here where I live and go up and down a steep hill in snow with no chains and only 2wd with factory posi differential although I don't advise it.
Does anyone need pictures of snow shoes, hunting boots or other cold weather gear..
recommend auto stuff, yeah it's basic * Flares + Reflectors, *a few Water Bottles, * Boots (water proof) aggressive tread, * Wool Blanket + heat blanket, * Tire tools that work, * Jumper Cables, * Tow Strap 12'-25ft, * Tire repair kit (for nails) Tire Pump, *Flashlight + xtra Batteries (check), * Coat Insulated, * Some Food / Granola bars, * Keep tank full, * Good Spare (check), * Good all terrain Tires (check frequently) * Spare Engine Oil & Tranmission Fluid if auto etc... I'm sure you can find a list... might want to add CABLES / CHAINS for unexpected snow! I've seen hail and snow @6000ft in JULY!
And a picture like these are worth making you start a small box kit for your car/truck now! Small suitcase would keep many clothing blanket stuffs clean / dry.
