WHICH TOW VEHICLES IT FITS: 14 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 390DS's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

FINDING ONE

Findable: a few listed nationwide most weeks. Why: East to West is a volume manufacturer; still in production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Heaviest dry weight in the line - two bedrooms, two full baths, loft and a 3,115 lb pin that needs a serious dually.
