Yeah it's a warrenty item but we have to use the truck every day to haul the 4 wheelers to the trail head. And its missing it's dpf and egr. Lol it seemed to get better so we are going to drive it home at the end of the week and just let our dealer work on it.

Wasn't really planning on going to durango.

Did you get it figured out?

If you haven't figured this out yet I had Dodge 2500 charging 17 V the other day and it was caused by resistance built-up by bad connections at battery

Cleaned connections on both batteries and had 14 idling when done . They also have batterie temp sensors that report to the PCM
