[QUOTE="TrailWhale, post: 1883193, member: 19177"] I have towed my 2018 over 30,000 miles and have not had any issues with dead batteries or transmission failures. Here is why, and why I did. First, a charge line is a MUST! It connects from the motorhome trailer plug to a one way breaker and then to the battery. The breaker allows for wire protection and prevents voltage feedback from the truck to the motorhome. The second thing I did…..and I think is the biggest thing…..instead of using my trucks tail lights and brake lights as the “trailer lights” when being towed, I got an inexpensive tailgate light bar off amazon. It has running, stop, and turn functions. This is tired directly to the plug on the front of my truck where the cord from the motorhome plugs into. This keeps the trucks brake lights, and tail lights from being activated and in turn keeps all the trucks modules from waking up. Now, on a diesel pusher motorhome there is already an air brake line at the rear that you tap into and run into the trucks engine compartment and T into the brake booster. This is how you properly do a supplementary brake system in the truck. The ones that sit in the floor and attach to the brake pedal are prone to failures if not installed correctly. If you are towing the truck with a gas RV, then the one that sits in the cab is an easier option, there are some cable systems but unless those are routed properly then they don’t work at all. But using either of those presents the issue of the brake pedal being pressed and therefore all the modules waking up…..this is why batteries die while being towed. My first motorhome was a gas class A, and I used the floor mounted brake system. I also installed a “brake light cut out” so that when it was being towed, I would flip the switch and the brake lights would not illuminate and not wake up the modules. I know this is a long reply, but it’s information that may help someone and hopefully not lose their truck Or motorhome. [/QUOTE]
