Question:

I just ordered RVI74FR and wanted to know if the circuitry includes protection from back-feeding power to the motorhome. I see a separate product, Roadmaster 690 Single Park Light Diode, that is used to allow only one way power flow, but not sure if it is needed with RVI74FR. thanks very much

Hey Fred, welcome back. The Curt RVi Series Towed Battery Charger+ for Flat Towing item # RVI74FR does indeed provide backflow protection. You won't have to worry about damaging your motorhome when using this on your 2020 Ford F-150.

Adding the Roadmaster Single Park Light Diode item # RM-690 to the Curt item # RVI74FR would be redundant.
