Yep, Alternator & Battery are the things most likely to leave you stranded. That's why I'm a big fan of dual independent alternators & batteries. Easy to do it with these trucks. https://www.dcpowerinc.com/collecti...dillac-escalade-1999-5-7l-v8-optional-124-ampNothing like your alternator going out when you are driving through wheat fields in the middle of NOWHERE . Luckily i was able to get to an Oreillys where i then got stranded but they had ONE alternator and it happened to be the exact one i needed and the brand i wanted.
