Grand Design Momentum 394G

Still in production. A used 2023 would run roughly $74,500.

dry weight 16,400 lb + fresh water (98 gal, full) 817 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 394G's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

These verdicts assume 2 people aboard with typical gear. See the margin for your truck and your crew →

A missing row means the maker never published that figure: unknown, not zero.

Grand Design (Mixed tier): Grand Design's toy hauler family, spanning four sub-series: the flagship M-Class fifth wheels (the plain M/MS/TH codes), the lighter G-Class fifth wheels (3xxG), G-Class travel trailers (2xG/3xG), and the entry MAV travel trailers. The premium fifth wheels are laminated aluminum-cage coaches on par with Solitude; MAV is a lighter traditional build, which is why the line as a whole reads mixed rather than uniformly better.

Patient search: weeks of watching, and probably some travel. Why: only one model year; still in production. Estimated from build volume and production span, not a count of live listings.

G-Class fifth wheel: 15 ft garage on the 22,500 lb chassis — G-Class value at M-Class size.
