I towed a JK behind my Class A for 4 years. There was a lead in the interconnect between the vehicles that tied the 12V from the motorhome to the 12V in the Jeep. This lead was only hot when the motorhome ignition was turned on.Does anyone have any thoughts or suggestions? I'd like an idiot-proof way to make sure the Jeep battery stays charged and I don't need to do anything special when I'm towing multiple days. In your response, please keep in mind that I know more about how the systems work in my motorhome than I do about how a car works under the hood!
That solves your "drain the moho" battery possibility when leaving the vehicles connected overnight or for days, yet still powers the braking system in the Jeep from the moho during towing.
My moho was on a Ford F-53 chassis, and I think one of the leads in the rear towing "harness" was a Ford factory harness wire triggered by the ignition as described above.
