KZ Spree 321RKS
Sticker was $35,515 in 2015. Out of production since 2015, so the used market is the only way to buy one. Estimate assumes a 2015 unit.
dry weight 6,680 lb + fresh water (40 gal, full) 334 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.
Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 321RKS's published weights held steady.

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.

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.
Double-slide rear-kitchen couples trailer; the biggest cargo margin of the early Sprees.
