I was told an interesting story by a friend who owns a very nice and fairly new Prevost & Class A only resorts.
Apparently, Prevost coaches are NOT class A coaches and some resorts have asked to see the title which says "bus conversion". Apparently he was turned away from a very nice RV Resort because of this. He complained of course and the resort said it has to change the by-laws to include Bus Conversions. I was under the impression that Prevost are Class A conversions.
