There is only one situation in which I prefer a Prevost; driving on salty roads. Newell has a steel chassis structure overlaid with aluminum skin. The two metals are separated in various ways to prevent corrosion due to dissimilar metals, especially in the presence of salt and moisture. If that separation fails and you drive on salted roads you will get holes in the aluminum skin amazingly quickly. On the older coaches that used polyethylene film as the separator it would be wise to verify its integrity before venturing near salt. Prevost use materials of construction that don't have this issue, they will however be heavier.

That's good to know.  I just had my entire coach refit with new metal around bottom and tops of bays.  Plus whole rear section when I put in new Tranny cooler and Radiator.  Learned the hard way with Country Coach.  They did a real good job treating the chassis frame and main cross members but the bay areas are just exposed steel.   We use to live in Michigan and used our Coach all winter, it was a lot of fun to have a park plow out a place for us to park.  The individual I bought it from warned me about salt, I didn't heed his advice and literally paid for it.    

When you say older Coaches, what numbers and below?
