[QUOTE="Zaairman, post: 834739, member: 2463"] Check the connections at your batteries. I had similar issues with mine, turns out the negative clamp on the passenger side battery was loose. I also have Costco batteries. I haven't had stellar luck with them, but with 3 year free replacement per set no questions asked, I can't complain too much. I think my first set lasted a little over a year before needing replaced due to being drained down all the time cause of the issue above. Second set lasted 2 years and 11 months before one wouldn't hold a charge. My truck also sits a lot like yours (sometimes 3-4 weeks at the most). That, combined with how hard these trucks are on batteries makes me think that is why they are dying early. I also installed a battery tender ($25 @ Walmart, ran the plug out by the block heater cord) that I will plug in if I know the truck will be sitting over a week. [/QUOTE]
