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

Scarce: months of watching; be ready to fly and drive it home. Why: only 2 model years; 17 years out of production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Sister plan to the 40 QDH from the same two years, with a different rear-bath arrangement. Same caveat: 32,000 lb is thin for a 40-footer.
