FINDING ONE

Findable: a few listed nationwide most weeks. Why: Forest River is a volume manufacturer; only 2 model years; still in production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Newest XLT plan; Forest River still lists wheelbase, LP and awning as TBD, so treat those as unknown.
