    I recently pickup a Warn M8000 winch. I am mounting it on a reciver winch plate so it can be run in the back & front. I am usually 2 gauge welding cables for the power cables off the battery. The truck has a stock replacement battery & stock alternator. I am I going to kill my battery & alternator the first trip out? I will probably be doing multiple pulls each time I go out. Should I upgrade to a dual battery setup, running them in parrel? And will the stock alternator be able to charge 2 batteries? Thanks for your help.
