Thanks, rfs56trk, Unfortunately, I understand what you are talking about. I tend to get caught up in the mechanical side of "Can I do it?" and usually lose sight of "Should I do it?"
I drove my truck for a couple of years with manual 4 wheel drums, and they did surprisingly well. I have rebuilt the rears completely, and have the front disc upgrade for reliablility. There are far more idiots on the road now.
Thanks for your advice.
