We have an opportunity to buy a '92 27' Mallard Class C with only (unbelievable) 4500 miles on it. It belonged to an elderly man (1st owner) who passed away and relatives sold it to the second owner who put 4500 miles on it and because of family problems must sell it. It's going for $19,900. Opinions about the RV and the deal.
Lack of use would be a big concern. Try every appliance, water heater especially, and if you dare, taste the water coming out the pipes. From such limited use over 8 years, things tend to grow in strange places. The hoses and tires probably need replacing from dry rot. I know things change just from over the winters let alone 8 years. Please don't let me talk you out of it, I am a "the glass is half-empty person" by birth. If you choose to buy it, you'll learn more the first year than in ten with a new one. good luck.
