WHAT ONE COSTS
$115,800est. used (2025, 1 yr old)

Sticker was $160,786 in 2025. Out of production since 2025, so the used market is the only way to buy one. Estimate assumes a 2025 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~16,881 lbestimated as towed, for 2 people

dry weight 15,455 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 around18,760 lb (10% margin)
GVWR (the sticker maximum)18,500 lb
Tongue weight, loaded~3,168 lb (19%)
Cargo capacity3,045 lb
WHICH TOW VEHICLES IT FITS: 16 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 38FLGS's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
