FINDING ONE

Patient search: weeks of watching, and probably some travel. Why: 8-year production run; still in production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Shorter two-slide rear-bedroom Super C - the easiest DX3 to park while still on the full 33,000 lb chassis.
