Had a friend inherited 2 Class A Winne's with 440/727's. The Scrap yard would not let him even bring the barges on their parking lot with the 'Black Water' tanks still in the frame. Its like $8,000 for them to scrap one that has the tanks under. Hazardous Waste fees.
And with all the wood inside, the scrap value is not much so my friend took them apart and got a lot for the aluminum, chassis and running gear. No one wanted the 440's on Craigslist.
