Isn't High Mileage Still a Problem on DP's

If you have 100,0000 miles on an MH, is it kind of "road beat"? Lets face it, MHs do take a beating on our, and other countries roads. And, how many miles a day can you drive a day, and keep it up? My non freeway miles is 400, and I was beat to death the evening. Has a MH with 100K, that is 5-7 years old, has been nearly lived in full time? You need consider the wear and tear on the interior, and the flexing of the house part itself, and how do you determine if the house part is still structurally sound? I, and probably a lot of others on this forum, have been on some very nasty roads. We know how punishing they can be. high mileage may be fine for the drive train, but what about the house part, and the wear and tear of that much living? Just opening and closing cabinets and drawers wears the finish, and hardware. Just like a S & B house, everything has a finite life time. Door hardware, cabinet hardware, everything that moves, or has a moving part, has a lifetime. Just say-in, buyer beware.
