Many modernizations took place on this 1957 Caravanner while she was at The Works.
She was a park model, so the only 12 volt was an overhead 1156 bulb that allowed for lighting while plugged into the truck. This was intended for set up purposes only and not task lighting. We put in an entire 12 volt system to control lights, a Fantastic Vent, a water pump and an on demand water heater. A converter and 100 amp hour battery were added also. Off the grid is now no problem.
