    That's an easy way, or if you want to keep one isolated as a backup you can wire in an isolator relay. Say you spend a lot of time running your radio and want to be sure you can start your truck afterwards. Wire the relay to be controlled by the main ignition(pink wire, green plug at bcm, stays on during crank). Either way works, just depends on your needs.

    Yep, depends what you need. I was just stating the simplest way, but you know that =)

    Simplest is best sometimes. Parallel is probably what most people need anyway. It's usually lake goers and tailgate partiers that need the isolated battery.

    I ran my yellowtop and Batcap in parallel with a 250amp alternator... no problems, even pushing 3200 watts for two hours.

    Isolated is a different story. I can give you a write up tomorrow if you need it. It's quite simple. I'm just too drunk and tired tonight.
