I'm running the 12vGuy set-up and it works great. You could assemble the same thing for a bit less money, but his kit made it easy. I mounted the switch under the hood as I just do not need to access it too often.

Do you have a wiring diagram for the kit?

You stated you had a stock alternator. This is kinda going backwards from what you want. Adding a second battery is an additional load on an already punny alternator. If you want some real power personally I would put the money into upgrading the alternator and wiring FIRST! Then buy a second battery if it's still needed.

Its a 3 position switch

Up - Alt charges both batteries & combines both batteries for extra power.

Middle - Alt charges both batteries but all power draw is from main battery

Down - completely takes the Aux battery out of charging circuit, makes truck act as if it only has one battery.

Ive had this kit for a better part of 6-7 years and it has never had any issues at all.
When would you ever use the "down" position?

This doesn't account for the idea of having a second battery in the backcountry if you leave an electrical draw on over night and need a way to start your vehicle in the morning.

You could use the "down" position if you want to preserve the Auxilary battery - perhaps listening to the stereo for an extended period of time and you want to keep the aux battery fresh.

Regardless I would still install a larger alternator FIRST! The batteries job is to start the car. Once the car is started all current should come from the alternator.

If you want a reserve battery I would install a switch with a solenoid so you can add it or remove it when you want.

A big alternator does not do any good if you can't start your motor. I run two batteries and they serve me well. When my key is in the off position, the solenoid disconects my aux battery. I have left my headlights on and drained my main battery. I open my hood, switch the solenoid to self-jump, and start my motor. Tell me, how is a bigger alternator going to help me in that situation?
My alternator is just fine and charges my system adaquetly. I was just after the extra battery capacity and back-up battery security. That is what I took from the OP question as well.
