Question:

I have a small home built tear camper with a deep cycle battery. I want to be able to charge the battery from the tow vehicle when on the road. The trailer lights are wired with a four pin plug. There is no converter in the trailer. What parts do a I need to be able to charge the battery from the tow vehicle? Thanks

Expert Reply:

To charge your trailer battery from your vehicle, I recommend the Roadmaster Battery Charge Line Kit # RM-156-75. This can be run to 5 way connection on each side like the Hopkins Endurance 5-Way Flat Trailer Wiring Kit - Vehicle and Trailer Ends - Ergonomic Design # HM47890. This will give you a clean connection of both sides to run to your battery terminals.
