Battery problems on 2010 Dodge Ram 2500

I have less than 25,000 miles and had to have the second battery replaced. First in Jan., my driver's side went out, now Nov., the passenger's side. Both times, truck went dead....any ideas, the dealer replaced one each time.

If one battery is defective the other will soon follow because they share the same load. The bad one drains from the good one and it too will fail. I may be wrong but i say always replace both at the same time. Same brand, same specs.
