l drove from Fort Collins, Colorado to Laramie, Wyoming on Hwy 287 for many years with a 2wd., 3/4 pickup, limited slip rear end, V bar chains, snow tires and a 3406 Cat engine block in the bed. Went around the gates, even in the blizzards. Only problem was the snow would pack in the grill and overheat the engine, and had to clear it out often. I was young and had a good looking wife !
