Regarding your original question, I have owned both a 1991 (HF2A) and a 1997 (HF2AV). Both trucks had Goodyear Duratracs.Does anyone with experience driving both versions have feedback? Is the HF2A noticeably less-good in the snow/slush/ice? Where/how/when do you notice the difference?
I live on a fairly steep hill with a stop sign half way up. In frozen rain/icy slush I would occasionally have to lock the center diff in the 91 to get the truck rolling from a dead stop on the hill. With the 97 it just goes.
That being said, any modern AWD vehicle will perform better on road in bad weather conditions than any 30 year old truck...until the snow gets deep.
