WHICH TOW VEHICLES IT FITS — 87 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 21BH's published weights held steady.

FINDING ONE
Patient search — weeks of watching, and probably some travel. Why: Forest River is a volume manufacturer; only 2 model years; 15 years out of production; an uncommon body style. Estimated from build volume and production span — not a count of live listings.
THE READ
Rare two-year hard-bunk Roo. No published MSRP found.
