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
~9,196 lbestimated as towed, for 2 people

dry weight 7,770 lb + fresh water (75 gal, full) 626 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

You want a tow rating around10,220 lb (10% margin)
GVWR (the sticker maximum)10,000 lb
Tongue weight, loaded~1,420 lb (15% — high, eats payload)
Cargo capacity2,240 lb
WHICH TOW VEHICLES IT FITS — 37 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 311THR10's published weights changed mid-run.

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

KZ (Mixed tier): KZ's toy hauler line (Thor Industries), sold as Sportsmen Sportster through 2016, Sportster/Sportster 100 from 2017, and Sportster X since 2025. Construction is mid-pack for the segment — aluminum-framed laminated fiberglass walls, a 3/8" walk-on roof and a heated, enclosed underbelly — with a Tuff Ply garage floor and diamond-plate wall protection that hold up well. KZ's assembly quality is uneven unit to unit, which is why it lands in the middle rather than at the top.
