I dont reccomend shoveling snow from MA roads into your truck bed,unless you dont mind seeing it rot away by spring!!!...its saltier than the Atlantic and has nasty chemicals like calcium and other corrosive stuff in it that will eat steel away rapidly................................................................................................I have had a few 2wd chevy pickups and for the most part they sucked in ice and snow,with no weight in the bed...one that had a posi loved to do a 180 when it locked in under throttle suddenly,but I did like the posi better than the open diffs ,they do offer better chances of not getting stuck as easily,but you must feather the gas around corners or risk ending up facing the wrong way while your still going 30 mph!.............................................My dad drove old pickups for work that were only 2wd,at the gas company--he HAD to be able to get to the propane distribution plants when needed no matter the weather conditions,so they put studded snow tires on them,and used bar lug reinforced tire chains when the snow was deep,or it was icy,and they put a block of concrete that weighed about 1000 lbs in the back of them....................................................................................................I remember vividly taking a ride in a '66 C20 pickup he had set up that way with 292 & a 4 speed,one snowy day up a huge hill in my hometown about 1/2 mile high,we were in second gear passing all the cars that spun out and had slid backwards and landed up against the curbs or in the ditches--we never even spun a wheel all the way to the top!...................................but I much prefer 4wd in snow,my 4x4 is a worthess cripple in 2wd,especially with the plow on it and nothing in the bed to weigh it down...at every stop sign you'll sit there spinning ,praying it'll move and you wont get T-boned by oncoming cars!....
