Mike, my very first pickup bought in 78 was exactly as you described, 66/C10/250/3-spd/3.73 long fleetside. It was a solid, good running/driving, dependable, economical pickup. I made a few small repairs and had it repainted. I could probably still be driving it but I traded it in 81 for a LUV. (I was young.) I agree the 3.08 is pretty steep for the 6, especially with a full load of firewood. OD seems the way to go. Good Luck! :p
