Travel trailerbuilt 2018–24Mixed build tierCommon on the used market
WHAT ONE COSTS
$38,000est. used (2024, 2 yr old)

Sticker was $55,711 in 2023. 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
~7,670 lbestimated as towed, for 2 people

dry weight 6,370 lb + fresh water (60 gal, full) 500 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 around8,525 lb (10% margin)
GVWR (the sticker maximum)8,200 lb
Tongue weight, loaded~1,048 lb (14%)
Cargo capacity1,830 lb
WHICH TOW VEHICLES IT FITS: 56 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 260UML's published weights changed mid-run.
