HOW IT'S BUILT — 4/5
WallsLaminated fiberglass
FrameAluminum
RoofWalk-on
UnderbellyEnclosed

KZ (Mixed tier): KZ (Shipshewana, Indiana; a Thor Industries subsidiary) pitched Spree as its "luxury lightweight" travel trailer, and the build was genuinely a step above the budget tier — aluminum-framed laminated gelcoat fiberglass walls, a 3/8" walk-on roof and a heated, enclosed underbelly, all backed by KZ's 2-year hitch-to-bumper warranty. Unit-to-unit consistency was the weak spot, which is the usual KZ story, and the line was retired after 2018 when Connect and Escape took over the segment.

FINDING ONE

Findable — a few listed nationwide most weeks. Why: KZ is a volume manufacturer; only 2 model years; 11 years out of production. Estimated from build volume and production span — not a count of live listings.
