WHAT ONE COSTS
$98,100est. used (2023, 3 yr old)

Sticker was $152,564 in 2022. Out of production since 2023, so the used market is the only way to buy one. Estimate assumes a 2023 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~16,174 lbestimated as towed, for 2 people

dry weight 14,540 lb + fresh water (100 gal, full) 834 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 around17,975 lb (10% margin)
GVWR (the sticker maximum)19,000 lb
Tongue weight, loaded~3,482 lb (22%)
Cargo capacity4,460 lb
WHICH TOW VEHICLES IT FITS: 18 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 V3911TK's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

HOW IT'S BUILT: 5/5
WallsAzdel composite
FrameAluminum
RoofWalk-on
UnderbellyEnclosed

KZ (Mixed tier): Venom was KZ's flagship fifth-wheel toy hauler (Thor Industries), built with aluminum-framed laminated sidewalls over Azdel composite, a walk-on roof and a heated, enclosed underbelly, and specified like a race hauler — 100+ gallon fresh tanks, dual 30-gallon fuel stations, generators and 88×96 cargo doors. The engineering is above the segment average but these are 13,000-15,000 lb trailers with heavy slide and suspension loads, and owner reports of slide, frame-flex and delamination problems are common enough to keep it out of the top tier. Absent from the 2025 lineup.
