Does the shell even matter?

[Patrick McGowen]

I am looking at a pre-1976 mobile home. I realize there are issues with the standards that were implemented in 1976; probably better to demo than move. But if the wiring, plumbing, siding, roof, windows, doors, flooring, appliances have been replaced, what makes a 1970 single wide any different in value from a 1980 or 1990 of same size in same park? Thanks
