Probably about as good as the rear-wheel drive trucks the folks down there were trying to drive in 2 feet of snow. I refused to pull any 2WD trucks out of the ditches stating "I'm sorry, I can't fix stupid". I probably pulled 25 cars out of jams in my 4WD GMC truck those 2 weeks.
ya. my first pickup was a 1969 chevy c-10. it got totaled before i got to try it in bad weather.
2nd one was a 74 c-10 with a 350, which was recieving a constant oil change. every 3 weeks, i'd dump 3 qts of oil in it. she had 287k or so when i got her......just about 300k when i sold her. she's still running today...still that same leaker.
anyway.......she was 2 wheel drive, with a 3 speed on the column.
tire chains baby!!!! never got stuck.
well......did get stuck once. just kept spinning em till the chains dug down to the ground, then i was away.
after that was a 1970 c-10 4x4, with a small block 400, a 4 speed with granny gear, 4.56 diffs. front was a dana somethign or other limited slip, the rear was another dana something or other, posi. THAT truck is the only truck i've ever owned that i miss.
