How many of us are there? Owners of Dodge based RV's?

@Capt Steve -- For the LED clearance lights, I recommend adding a second ground/negative wire, in addition to the power/positive wire. Most motor vehicle LED lights are manufactured with only a single +12VDC wire, on the assumption vehicle will have/use a -12VDC body/chassis ground. The aluminum skin (and any metal framing) on motorhomes is usually not sufficient for reliable operation of exterior lights.
