Tiffin (Better tier): Tiffin's mid-line diesel pusher: Crane Noble all-composite sidewalls, tubular aluminum framing, steel basement and a Freightliner PowerGlide raised-rail chassis with ZF independent front suspension - genuinely well built, with the caveat that post-2021 Thor-era service is not what the family-run years were.

THE READ
