I have a friend here in TN that has a winnebago with a 6.2 diesel for sale. It also has a gear vendors in it. He has been living in it while building his house but now wants to let it go. It has been sitting awhile, but he says all appliances and generator work and it could probably be had for 3K or less.
PM me if you are interested and I will give you his number.
