Many Winnebago motor homes are now delivered with the Schumacher 55 Amp Power Center that includes a single stage converter/charger not generally considered by many to be the best option for deep cycle battery charging.  Since there is no multi-stage charging option for these units,  many of our customers have installed a stand alone Boondocker 4 stage converter/charger adjacent to the Schumacher.  This simple procedure converts a Shumacher to a 4 stage "Smart" charger.
Special thanks to our customer Marty Davis for taking the time to document his work.
