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
~7,285 lbestimated as towed, for 2 people

dry weight 6,110 lb + fresh water (45 gal, full) 375 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 around8,095 lb (10% margin)
GVWR (the sticker maximum)7,882 lb
Tongue weight, loaded~1,052 lb (14%)
Cargo capacity1,740 lb
WHICH TOW VEHICLES IT FITS — 52 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 M251BH's published weights changed mid-run.

Heartland (Mixed tier): Mallard was Heartland's entry-price laminated trailer - Azdel walls, aluminum cage and a walkable vacuum-bonded roof put it above stick-and-tin rivals at the same money, but fit-and-finish and dealer support were ordinary and the line is now dead.
