WHAT ONE COSTS
—price not published

The maker never published an MSRP for this floorplan. Unknown is not cheap — treat any asking price against comparable models, not against zero.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~10,094 lbestimated as towed, for 2 people

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.

You want a tow rating around11,220 lb (10% margin)
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.
