I hope I can get opinions from the group, we are going to look at a 1987 Minnie Winnie, never seen one up close, and don't want to make a mistake out of ignorance. Can anyone tell me about it? Definitely things like how many storage tanks, what is their capacity, any quirks, special places to look for deterioration, that sort of thing. How long is this? From the inside (it only has the cafe table and 2 small seats, no couch) it looks smaller than 22 ft. Any thoughts would be appeweciated, thanks!
