    I have a 2004 chevy tahoe with the stock alternator and I was just wondering in order to add a extra battery do I have to upgrade the alternator first?

    The stock alternator can handle 2 batteries just fine under normal conditions. If you are going to run an occasional winch that is OK too but if you are running extra accessories all the time like a big Amp or power inverter for power tools etc. then you need a bigger alternator.
