I recently acquired a Coachman Class C based on a 1985 Ford E350. Of course I would love to find copies of the owners manuals but it would be great to know the water, grey water and black water capacities. So far everything works. Had a couple of house batteries that the previous owner had not monitored them. She had several items replaced in the last year, generator, tires, 2 coats roof done professionally, new day/night window shades all around. It drives well.
