So the voltage regulator was bad on the 2-week old alternator! Replaced it under warranty and upgraded to 94A alternator. So far the belt squeak is gone and voltage gauge reads normal. We had a full system check (coach) by RV shop and everything checked out. 2 fire extinguishers on board in case

Regarding the well known 454 alternator belt issues, I was reading the chassis service manual. Found that the alternator is to have a higher belt tension than the ac or PS belts. It is also to be re-tensioned after 30 minutes/15 Miles of driving, 8 hrs/240mi, and re-tightened every 200 hr/6000mi. I confess I did not know this procedure and may have been part of my belt failure experience. I will be checking water pump bearing situation this week
