Just wanted to introduce myself. I just purchased a 2018 Laramie ecodiesel. It's the first diesel I've owned. Recommendations from my son that uses a 3500 with the Cummins diesel. I'm still learning about vehicle but already twice I must have left something on as the battery would be dead in the morning. Truck is like new, only 7500 miles. I'm leaving for Fla tomorrow so I'm hoping everything will go well.
