Hello, I own a 1997 Rockwood 1640. Does anyone know where I could find a wiring schematic of this camper? I'm not even sure if it has to be specific to this camper. I would even be happy with a generic schematic. I'm curious to find out how the battery, power converter, and the tow vehicle are all inter-connected? I'm not sure if my camper is wired correctly. I bought the camper without a battery, and I am going to add one. It appears the wiring was altered to eliminate the battery, and I'm not sure how it would be put back into the loop? Is the TV suppose to charge the battery when in tow? A standard 4-pin connector was spliced in. A retro-fit so to speak. Will this 4-pin connector work with charging the battery from the TV? Sorry for all the questions, but I am unfamiliar with how all this works. Thank you.
