how bout.. sizes of the water potable and gray tanks..year of appliances if any..if it has a hood system has it ever been inspected? cleaned? by the way if it does have a hood system take the filters down check to see how the grease is under them(or over so to speak) you may want to check the ceilings too.. when I was looking I found what I thought was A good rig ..but I noticed that the ceiling didnt look quite right. when I pushed up on one end ……the water just ran out of it…no thanks !!
