Heartland Mallard M33

Travel trailerbuilt 2016–25Mixed build tierCommon on the used market
WHAT ONE COSTS
$42,300est. used (2025, 1 yr old)

Sticker was $45,425 in 2021 — out of production since 2025, so the used market is the only way to buy one. Estimate assumes a 2025 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~8,765 lbestimated as towed, for 2 people

dry weight 7,590 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 around9,740 lb (10% margin)
GVWR (the sticker maximum)9,600 lb
Tongue weight, loaded~982 lb (11%)
Cargo capacity1,978 lb
WHICH TOW VEHICLES IT FITS — 40 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 M33'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.

FINDING ONE

Common — usually several for sale within a day’s drive. Why: Heartland is a volume manufacturer; 10-year production run. Estimated from build volume and production span — not a count of live listings.

THE READ

A nine-to-ten-berth bunkhouse under 9,600 lb GVWR, which is the whole pitch. Skip the 2016-19 cars - at 8,600 lb GVWR they run out of cargo before the family is loaded.
