My battery gauge started running around 19 all the way in the red. My alternator was bought new in november 2011. After I turned truck off for about 20 minutes it went back to around 14 to 15. What could the problem be.

It sounds like a bad voltage regulator. Have the alternator tested at a local parts store. Most can do it on the car and do it for free. If it continues to do that, it will burn up wiring and damage things.
