WHAT IT WEIGHS BEHIND YOUR TRUCK

~14,571 lbestimated as towed, for 2 people

dry weight 12,603 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 around16,190 lb (10% margin)

Tongue weight, loaded~3,050 lb (21%)

WHICH TOW VEHICLES IT FITS: 19 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 325G's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

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.

OUR TAKE

G-Class fifth wheel: 15 ft garage in a 35 ft coach — best garage-per-foot in the line.
