WHAT ONE COSTS
—price not published

The maker never published an MSRP for this floorplan. Unknown is not cheap — treat any asking price against comparable models, not against zero.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~9,500 lbestimated as towed, for 2 people

dry weight 8,410 lb + fresh water (40 gal, full) 334 lb + propane + battery 200 lb + gear for 2 600 lb — capped at its own rating. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

You want a tow rating around10,560 lb (10% margin)
GVWR (the sticker maximum)9,500 lb
Tongue weight, loaded~1,152 lb (12%)
Cargo capacity1,090 lb
WHICH TOW VEHICLES IT FITS — 34 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 337RES's published weights held steady.

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.

YEAR BY YEAR — WHAT CHANGED

FINDING ONE

Findable — a few listed nationwide most weeks. Why: KZ is a volume manufacturer; only one model year; 10 years out of production. Estimated from build volume and production span — not a count of live listings.

THE READ

Rear-entertainment triple-slide with a king bed; 17' second awning optional. Became the S323RE for 2017.
