2010 Ram 3500 SRW 4x4 CTD mega cab with 57k miles since new. All recalls done and no problems until last month when batteries were dead from sitting for 3 months during my open heart surgery recovery. Put chargers on batteries for 2 days and got it started but wipers came on, stuck in 4th gear on 68rfe auto, CEL came on, check trailer connection warning displayed, and no power stuck in limp mode. Next day batteries were .16 V and dead. New batteries and 7 problem codes cleared and runs great again. Miss the days of jumpstarting and driving away. My point is it has been great but NEVER let the batteries get low.
