Jayco (Mixed tier): Jayco's pop-up line — DuraTek canvas ends on a powder-coated steel frame with a one-piece wood floor deck and extruded-aluminum bed platforms; budget construction, but a 2-year limited warranty and a huge dealer network. Jayco left the segment after 2019.

FINDING ONE

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

OUR TAKE

The top of the pop-up range — a hard-sided storage cabinet up front, 14-inch C-range tires and the only Jay Sport you could order with a bath/shower.
