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.

FINDING ONE

Patient search: weeks of watching, and probably some travel. Why: 9-year production run. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

A 41-ft couples plan with no bunks and no half bath - all the length goes into living space. The 2017+ cars are the ones with real payload.
