Does My Camper Battery Charge When Plugged Into Truck. Not only should you check pins 1 4 on the truck to see if you have charging voltage with it running. My new travel trailer meltedcorroded the 12v contact on the plug.
The most common way you will charge your batteries is when you are plugged into 110v shore power. So there is a trade-off in keeping the house battery plugged at all times. Even if my truck could charge my camper battery I would not count on it.
However that charge will not be enough to sufficiently charge a depleted battery.
The electrolytes of your RVs house batteries get consumed and decrease its condition. GM trucks do not come from the factory with the fuse for the charging circuit in the fuse box. If you have a 7-way connector between your towing vehicle and your RV that powers the electric brakes running lights turn signals. Alternatively a campers battery could be charged directly through the tow vehicles alternator solar power or even wind power.
