FINDING ONE

Findable: a few listed nationwide most weeks. Why: Thor Motor Coach is a volume manufacturer. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Shortest of the late Siestas at under 25 ft, with a 14 ft 6 in awning in the early years. Compact enough for most state-park sites.
