What are you guys running for batteries.
Same here in Vegas with the 2.5 years of life. Heat kills 'em. May get longer if you can garage the truck, but my LBZ doesn't fit. Just replaced mine last month with Walmart Maxx. I've had Deka (CAT), Bosch Premium and now these Walmart Maxx. The original AC Delco batteries made it like 5 years, but the truck was in covered parking and often in SoCal. Plus the original AC Delcos were much better back then, imho.Here in the Arizona desert battery's never last more than 2 or 3 years period. I just keep replacing them at Costco when they die . They always die in the warrantee period and they replace them free.
