Mom's been driving it to work this week, it may roll over 100 miles before the weekend is over!
My dad has driven trucks forever and has had 2wd trucks as long as I can remember. You only really need it once maybe twice a year, it just isn't worth it. If we lived up in northern CT where it actualy snows, and went off roading it would be worth it. But for normal street use its a waste, imho.
Heck I have been down icy back trails trying to get to fishing spots in the MB's! At the end of the trail all you see is mud covered 4wd pick ups and a rwd MB, always get funny looks.
