Second battery option

[cthompson]

Is there any positive to getting a second battery in my truck if it has that option?

Only if you have lots of toys, or a diesel. Diesels have electric grid heaters and/or glow plugs to suck the batteries down right before you hit the starter. Gas rigs just have the heated seats and the starter. If you have a little self control you can start it before powering the seats. 😉

If you will are planning to install lots of electrical accessories, especially ones you will use with the engine off, it may be beneficial. These might include: winch, off road lights, high powered stereo, 2 way radios, inverter, etc.
If you're just going to drive it around like a car then I see no reason for 2 batteries.
