dry weight 19,100 lb + fresh water (140 gal, full) 1,168 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 around23,410 lb (10% margin)
GVWR (the sticker maximum)23,500 lb
Tongue weight, loaded~4,147 lb (20%)
WHICH TOW VEHICLES IT FITS: 8 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 396DB's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

UnderbellyEnclosed
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.
