I have a friend that full times in a 1998 38 ft Dutch Star. It is a very nice MH, went to Alaska with him in 2006. The two AC's cool fine and both have heat pumps. His inverter just went and it will be replaced next week. Roof is original and all seams are covered with Eternabond tape and has never leaked. Domectic refer was replaced several years ago with another Domectic. He averages 8.5 mpg. If the MH is in good shape and everything works I would pay a little over Nada. Print the Nada prices and show it to the person selling the MH he is probably not aware of what the MH is worth if it is an estate sale.
