Duel Battery Setup?

Hey All,

Does anyone have any have any ideas on how I would go about putting a duel battery setup in my '76 chevy c10 4x4 I would like to have both batteries running off the same charging system but want to keep them isolated. I would like to have one running all the stock truck functions and etc. and the other I want to run all of my accessories (winch, lights,and etc.) if anyone has any ideas or plans I would be very greatful.
Thank you in advance for any help!
