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
~10,787 lbestimated as towed, for 2 people

dry weight 9,987 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 around11,990 lb (10% margin)
GVWR (the sticker maximum)11,569 lb
Tongue weight, loaded~859 lb (8% — low, watch for sway)
Cargo capacity1,582 lb
WHICH TOW VEHICLES IT FITS — 29 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 406FLR's published weights held steady.

FINDING ONE

Common — usually several for sale within a day’s drive. Why: Gulf Stream is a volume manufacturer; 12-year production run; still in production. Estimated from build volume and production span — not a count of live listings.

THE READ

Front-living lodge with a window bench and theater seats. The Trailmaster sheet swaps the hitch-weight and NCC columns relative to the Kingsport sheet (795 lb hitch / 1,582 lb NCC vs 1,582 / 795), so both the pin weight and GVWR here are less certain than usual.
