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: 12 years out of production. Estimated from build volume and production span — not a count of live listings.

THE READ

A seven-year 40-ft plan spanning the first Phaeton generation. The 2013-14 cars with the 380 hp engine and 35,320 lb chassis are the ones worth buying.
