WHAT ONE COSTS
$47,200est. used (2021, 5 yr old)

Sticker was $76,881 in 2021. Out of production since 2021, so the used market is the only way to buy one. Estimate assumes a 2021 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~14,902 lbestimated as towed, for 2 people

dry weight 13,268 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 around16,560 lb (10% margin)
GVWR (the sticker maximum)16,000 lb
Tongue weight, loaded~4,032 lb (27%: high, eats payload)
WHICH TOW VEHICLES IT FITS: 19 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 S36GWS's published weights held steady.
