As you discovered, Dodge does not turn off 12V feed (some manufacturers do.) As I did not want to give Dodge an excuse of "you modified the truck - your warranty is void" I found the 12v wire from the pigtail inside the camper and installed a relay to isolate it. I tied the relay coil to the running lights in the camper.
Start the truck - running lights come on - 12V is tied in by the relay. Turn off the truck - running lights turn off - 12V is isolated.
If you want, I can dig up the info on the relay. I got it off Amazon. Took me all of 15 minutes to install it. Never have to worry about leaving switch on and killing the batteries in the truck
