i find all pickups really suck in as little as an inch or 2 of snow unless you load the bed with some weight so dont be disappointed if it doesn't totally change it for you
with a bed full of blocks I can actually PLOW snow in my pickup in 2wd , no weight im sliding with an inch or 2 on the ground unless its super light stuff
really need to take tire advice from people in similar climates to yours or even worse in regards to snow fall amounts
