Ours is a 1998 Four Winds 5000 22rk (rear kitchen). I purchased ours for $14k nice inside and out. Came with with new Firestone LT tires and new batteries, and 36,500 miles on it, with a V-10,and no leaks. Came with all the manuals for everything, but actual MH operation.
Now the MH was only eight miles down the road when I bought it off Craigslist. When I drove it, I knew there was a handling problem, steering was way to lite. There were people standing in line when I bought it, felt lucky.
This was last September. Sine then I have invested another $4,000 in preventive maintenance of items at my request, and mechanics found bad tie rod ends and a leaky pinion seal. Steering is fine now. I've upgraded the converter to a three stage, radio to new do everything, backup camera, and new high profile toilet.
So, be prepared to invest more then the purchase price, at least a thousand or more in tax and license. But, I would drive it, and inspect for leaks. The one I bought was garaged and I also garage it, and continue to look for modifications. We get 9 mpg in the mountains, and 11 mpg on the flat. Hope this helps with the reality of older MH's. One nice thing and a reason we bought it: Is we can park just about anywhere. We've had five TT and two MH's. Both MH's have been short to allow better access where ever we go.
