Odometer Reset

I'm still looking for anybody else who this has happened to. I posted on here a couple of years ago the first time this happened and found nobody else. I had an RV repair guy come out and fix something on my RV when we were in a campground in Vegas and I asked him about the odometer problem. He told me it happens all the time and he said a Freightliner dealer could easily plug into the internal computer and get the true mileage. Like I already said, the Freightliner center said it wasn't so simple. I'm just trying to find out if anybody else had the issue and how they got it resolved. Sounds like I may be the only one.
