WHAT ONE COSTS
$109,200est. used (2026, 1 yr old)

Sticker was $151,711 in 2026. Out of production since 2026, so the used market is the only way to buy one. Estimate assumes a 2026 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~15,961 lbestimated as towed, for 2 people

dry weight 14,535 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 around17,735 lb (10% margin)
GVWR (the sticker maximum)17,700 lb
Tongue weight, loaded~3,152 lb (20%)
Cargo capacity3,165 lb
WHICH TOW VEHICLES IT FITS: 18 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 38KPTS's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
