It's time to replace the stock battery in my '12 fronty. The posts have got a lot of corrosion going on, and I'll be adding a winch before too long (plus all of the LEDs I use ~400watts or so). So, I've been thinking of sears platinum, or optima. Do any of you guys have much experience in this? I'm really wondering if I should go with the recommended size battery for my truck, but also wonder if I need to get something a bit beefier for the winch and other electronics. How big can I go, and it still fit? Thoughts? I'm hoping to go get one tomorrow.
