Hello, first time poster!
Recently I have started to notice that if I hit a decent bump in the road a chime will sound. Along with it the interior lights will come on, and a few seconds later the doors will re-lock. Nothing will appear on the dash to indicate that anything is wrong. I’ve looked around and seen that a lot of people are suggesting it may be a loose door latch or a faulty bulb connection. I have not found any definitive answers to help me narrow a solution down. If it is indeed a door latch how do I go about finding which one is bad? I’ve checked the latch on all my doors and physically they all seems to be the same. If it’s a faulty bulb connection, is there a sure way to figure out which one it could be? Thanks for your time!

Intermittent electrical problems are difficult to locate. I rec you begin by making sure your grounding points are clean and snug, and that your battery is securely mounted and doesn't bounce. Also check that your battery reads at least 12.6v static and 13.5v with engine running.
If you're fairly certain that the base electrical supply is good, then I think the fastest solution would be reading OBD2 using a scan tool with Dodge/Chrysler data. Your computer will log faults without throwing codes, but your scan tool needs the manufacturer-specific data load.
You could try asking parts stores to read your codes, or go to a mobile mechanic, or dealer, with a Dodge/Chrysler tool.
Has there been any wiring work done on the truck? Any mods that involved modifying the electrical system?
I would agree that checking for a faulty door latch is a good of a start as any. Perhaps remove the door panels and check the wiring going to the latches. Of course you won't know if you fixed anything until you hit a big bump.
