Thanks for the input.
Mar,
I put mine in the back. I ran the wire underneath the truck and up through the back. Walmart carries a black plastic battery case that can be secured. I do not know where else to put it.
An added benefit is that I have a portable winch that you can attach to a traler hitch receiver. That way I can use it in the back to winch backwards.
I also have a battery pack jump starter as well. Overkill, Yes. Let me tell you why. My wife and I were wheelin and were back in the woods about 6 miles on top of a mountian when the alternator went out. We had to hike out. I had my brother bring me a battery. He has a 2 wheel drive. Could not get anybody with a 4 wheel drive to help and it was getting late in the day. I did not want to leave my truck in the woods over night. So we hiked back up the mountain carrying a battery. It about killed me. Got back up, installed the new battery (which is why i have two now,) gulped some cold water way too fast and threw up. I can tell you from experience that if the alternator goes out the battery pack will start the car but it will die. If the battery just goes dead because of a loose connection you will be fine and it will recharge. I usually carry extra coolant, belts, hoses, air compressor, tools and such in the woods just in case. I am gald to have 2 batteries now and soon will have a backup alternator.
As we all know it is not a good idea to go wheelin alone and I usually don't but the wifey talked me into it.
