I used to have chains for my 2wd truck until one winter I had to use them. My father was scheduled to have prostate cancer surgery Monday morning and its an hour drive to the hospital on normal days. We went down to be there for support and over a foot of snow was dumped on us that weekend. He was supposed to be at the hospital at 6am so we had to leave their house at 4am. One chain completely broke going up the first big hill but luckily I had installed a lock rite which is an auto locking differential so the one chain was enough to make it up the hills although it pulled very hard to one direction a lot. I ended up beating up one fender pretty good when one of the cross chains broke loose on a steep part where I didn't want to stop. I ended up buying a 4x4 truck because even though I got buy with never needing 4x4 for over 10 years there was that one time I was away from my home and we had to go out.
Got in another snowstorm around the MD/PA state line riding with my cousins 4x4 and the state police let us though the roadblock since he had a 4x4 and the volunteer FD sticker but were turning a lot of people around.
