WHICH TOW VEHICLES IT FITS: 20 OF 95

Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 3603LFP's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

FINDING ONE

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

OUR TAKE

Rear-loft Platinum: a second sleeping level over the rear instead of a bunkhouse. Tallest Astoria at 13 feet, so measure your garage. GVWR derived as dry plus cargo capacity.
