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 V3815TK'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.
