FINDING ONE

Common: usually several for sale within a day’s drive. Why: Gulf Stream is a volume manufacturer; 12-year production run; still in production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Front-living lodge with a rear window bench, theater seats and a free-standing table - but only 795 lb of cargo left over.
