Slide-On Wiring
NorthRunner,
When wiring in the truck camper harness, you should isolate the truck batteries from the camper batteries when the ignition is off. I recommend a solenoid for this, mounted in the engine compartment. Don't let your RV dealer tie the slide-on "running lamps" into the Dodge running lamps line. You'll just blow out the dash fuse, 20 amp. There is dodge 40 amp relay in the PDC for this. If your not prewired with the camper package, you can pick up the line just behind the DS front wheel well. That relay is energized thru the Dodge when the parking lamp / Head light switch. Hope this helps.
