Appreciate the suggestions on the belt tensioner, particularly the one from Gene advising, "whatever you use to set the belt tension (a 2x4 - or a tensioner ;>) the bolts in the device (alternator, ac pump, ps pump) are what hold the
belt tight, not the tensioning device." That makes sense. Belts do elongate. To compensate, spring loaded tensioners come out now on most new vehicles. My other "tinker toy" is a 25-year old '88 Fiero GT. Fieros did not have automatic tensioners installed at the factory. Similar to the GMC, you can set the tension on the alternator belt and it might not be long before the belt starts squealing again. Here's the retrofit I installed to solve the problem: http://home.windstream.net/dodgerunner/Fiero1_files/BracketInfo.html
It's not a big deal but apparently, nothing similar is available for our motorhomes.
