Help-Unusual amount of rust on chassis-looking to buy

The other thing to consider is the old owners were snowbirds and not all the time was spent in Arizona. I've seen many nice looking coaches that were all rusted up underneath because they wintered along the Texas gulf coast (would be an easy drive from Nebraska.)

Many of those owners trade in their coach's after 5-6 years. Much longer then that and the rust starts showing up so much that it affects value.

Should you buy or not, hard to say. I just wouldn't pay "excellent" NADA for it.
