WHAT ONE COSTS
$68,100est. used (2018, 8 yr old)

Sticker was $113,781 in 2016. Out of production since 2018, so the used market is the only way to buy one. Estimate assumes a 2018 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
18,000 lbno dry weight published: its rating stands in
You want a tow rating around20,000 lb (10% margin)
GVWR (the sticker maximum)18,000 lb
WHICH TOW VEHICLES IT FITS: 14 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 Madison's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

Heartland (Better tier): Heartland's flagship luxury fifth wheel, rebranded Landmark 365 in 2015 - Azdel walls on a double-welded aluminum cage, vacuum-bonded floors, 8,000 lb axles and three A/C units; floorplans are named after cities rather than numbered.

FINDING ONE

Findable: a few listed nationwide most weeks. Why: Heartland is a volume manufacturer. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Four-year Landmark 365 plan; Heartland never published a dry weight for it on the model page.
