I like that "herd" comment. when teaching junior drivers to operate a fire truck (same style solid axle stuff) I would tell them to pick a point far down the road and drive in that direction. don't concentrate on the area 5 ft in front of the grille because you will constantly be correcting. stay between the lines but average it out. there will be some drift due to play in steering components and the generally how the road is crowned, cracks the tires want to follow etc. pay attention to the steering wheel feedback and do your best to counter that as required.
nowadays I drive a newer chevy with electric assist. I swear the old solid axle was easier to predict. if you take your eyes off the road for a sec you are in the next lane.
we have come a long way, haven't we?
