Also, with pick up trucks---- since they are so light in the rear, does everyone just load them with play sand bags or something during the winter for traction? I know we don't get much of anything in the winter, but when we do get stuff (icy sludge), pick ups are fishtailing all over the place.
I don't bother to load sand bags in our pickup, although we're in West Virginia (and not in the deep mountains) and not Buffalo or North Dakota. We're also retired and rarely go out in the snow anymore anyway just because the idiots make it risky. The pickup is 4WD, has all-season M&S tires on it, and that is good enough for our purposes. I don't even own a set of chains for it.
With 4WD engaged I have not experienced any issues with fishtailing, and suspect that any 4WD pickup that does has a driver with too heavy a foot. If I owned a 2WD pickup I'd never consider taking it out in any amount of snow, those things are bad enough in just rain.
I have some family in Buffalo, and if I did live there I'd probably have sand bags and chains but here it isn't needed.
