WHICH TOW VEHICLES IT FITS: 16 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 392MB'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

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

OUR TAKE

The five-slide mid-bunk plan and the only River Ranch that sleeps more than four. At 15,025 lb dry with a 2,455 lb pin it wants a dually or a serious one-ton. Awnings 21' and 15'.
