FINDING ONE

Patient search — weeks of watching, and probably some travel. Why: Thor Motor Coach is a volume manufacturer; only 2 model years. Estimated from build volume and production span — not a count of live listings.

THE READ

The bunk model: two full baths, one of them across from the bunks, plus two power slide-out storage trays. The only Tuscany that genuinely sleeps a big family.
