WHAT ONE COSTS
$39,300est. used (2024, 2 yr old)

Sticker was $59,265 in 2024. Out of production since 2024, so the used market is the only way to buy one. Estimate assumes a 2024 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~10,182 lbestimated as towed, for 2 people

dry weight 8,756 lb + fresh water (75 gal, full) 626 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 around11,315 lb (10% margin)
GVWR (the sticker maximum)11,970 lb
Tongue weight, loaded~2,058 lb (20%)
Cargo capacity3,214 lb
WHICH TOW VEHICLES IT FITS: 28 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 25ML's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
