I took my truck to a local ac shop to get it checked out and low and behold black death. He recommended replacing the compressor, drier, exp. valve, flushing the system, and recharging. He also gives a 1 year warranty on parts and labor. After I got home I looked on line and found replacement of everything from the fire wall forward is the recommended fix. My question is if there is still junk in there the system should show signs before my 1 year warranty is up right. If it fails then the warranty should cover it for year. This shop has been around for a long time and the man is well respected so it's not a fly by night operation. Some of my friends have used him and recommend him and have never had problems with him honoring any warranty work. Any opinions or answers are welcome.

You should look at replacing the condenser also. If you don't replace it, you should have a "hot flush" done which entails the opening of the liquid line and a pancake filter installed. Then you would run the system, recover the charge, and remove or replace the filter and repeat the process. The black death is actually the teflon rings of the compressor. They are hard to get out of the system; replacement of the condenser is the best approach.
If your shop has experience and the necessary equipment to perform an effective flush; and will stand behind their work. I would have to assume that they would not even make this offer if the "black death" issue was severe; it may just be burnt/dark oil. In the most severe cases a condenser replacement would be in order as the hard carbonized debris (true "black death") is not removed with flushing. Yes, such a problem with the condenser would present itself rapidly and be their responsibility under their warranty to resolve.
Ok thats what I thought. I just didn't know if was a slow process or what. Before a year is up would you recommend pulling the system down and checking the filter for any dislodged particles of gunk and maybe an additional flush if needed?
If the repair is done properly, that should not be necessary. Ask them, and follow their advice to maintain the warranty.
