You want a tow rating around7,290 lb (10% margin)
GVWR (the sticker maximum)6,558 lb

FINDING ONE

Findable — a few listed nationwide most weeks. Why: Forest River is a volume manufacturer; 10 years out of production; an uncommon body style. Estimated from build volume and production span — not a count of live listings.
