Well I've seen posts on it here before and didn't give it much thought until Sunday when it was time to leave and the truck battery was dead. Popped the hood, threw the switch/breaker and the truck fired right up. Time for a new truck battery and will remove the fuse for the cargo lamp that comes on every time you open the truck doors. Battery is original(8yrs), works fine if started each day, but I knew it was way past prime and had always carried a back up for such things when heading into back areas.
