Go over to TS and look up TacomaOffRoadGrl. She's got dual optima's under her hood to keep her fridge running when she's away from the truck. She did a nice job.

cptcrush added a second battery and isolator on passenger side under the hood. Check with him if he can provide any pointer.
Thanks for the tip!
I see the isolator, but I've never used one before so I'm sure on the wiring. Also wasn't sure what the circuit breaker was going to. Looks like isolator to yellow top pos terminal, but not sure looking at the pic.

I build alternators and setup charging systems for stereo competition so let me displace a few rumors and try to help out some.
1. Isolators are not required unless you intend to play the stereo while the vehicle is off and don't want to kill the cranking battery. Your amplifier won't appreciate the low voltage.
2. Running dual batteries is a good idea, make sure they are a matched set meaning same type and age. If one goes bad in 2 years replace both.
3. When running dual batteries they should be as close together as possible. Opposite sides of hood is allowable, one in bed other under hood will shorten the life of both.
4. Optima batteries do not have to be mounted upright nor do they require boxes, you can strap them under the bed securely and they'll be fine. Running a jump start access point would be a really good idea. Position the batteries so when they need testing you don't have to remove them first.
5. Dual batteries do not take the place of a high output alternator, they go hand in hand.
6. Grounding cables such as you see on ebay rarely do anything but add color.
7. Split the connections on the batteries where you can, like use the top post to connect to alternator, run the stereo lead to the side post. This lessens the corrosion and heat, therefore reducing the chances of bad connections.
8. On a dual setup make sure the alternator is charging one battery and the amps draw from the other. Both batteries can share one ground but don't forget to make sure the block and chassis are grounded. alternator-+-+-fuse to amps ground--------
