I'm new to this site and just seen the post about the dead battery in cold weather and want to tell you that i have exactly the same problem when the cold weather sets in. 2 years ago i installed a disconnect switch on the battery and now i can let the truck set for weeks without a problem starting it once i turn the switch back on but now it's getting on my nerves having pop the hood every time to disconnect and reconnect the battery now being it draws very fast sometimes. If anybody out there gives has a clue what could be causing it PLEASE let me know. Thank you in advance, quigley
