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
~5,237 lbestimated as towed, for 2 people

dry weight 4,103 lb + fresh water (40 gal, full) 334 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 around5,820 lb (10% margin)

Tongue weight, loaded~696 lb (13%)
Cargo capacity1,500 lb
WHICH TOW VEHICLES IT FITS — 71 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 NB18.3's published weights changed mid-run.
