WHAT ONE COSTS
$32,700est. used (2021, 5 yr old)

WHAT IT WEIGHS BEHIND YOUR TRUCK

dry weight 8,460 lb + fresh water (100 gal, full) 834 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

GVWR (the sticker maximum)12,995 lb
Tongue weight, loaded~1,336 lb (13%)
WHICH TOW VEHICLES IT FITS: 31 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 S29STT's published weights changed mid-run.
