Tiffin (Better tier): Tiffin builds above its price class - Crane Noble all-composite sidewalls over tubular aluminum wall and roof skeletons, a steel floor and basement structure, and full-body paint standard - and the brand's service reputation still carries it, though Thor-era (2021+) owners report slower parts support than the family-owned years.
