WHAT ONE COSTS
$75,600est. used (2025, 1 yr old)

Sticker was $104,932 in 2025. 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
~14,440 lbestimated as towed, for 2 people

dry weight 12,823 lb + fresh water (98 gal, full) 817 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 around16,045 lb (10% margin)
GVWR (the sticker maximum)15,000 lb
Tongue weight, loaded~2,954 lb (20%)
Cargo capacity2,129 lb
WHICH TOW VEHICLES IT FITS: 19 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 CT3.7's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

Heartland (Mixed tier): Heartland's 2024 value line - Azdel composite walls, aluminium-framed sidewalls, a walkable TPO roof and 190W of standard solar, but it is far too new to have any owner track record and Heartland's QC history is uneven.

FINDING ONE

Findable: a few listed nationwide most weeks. Why: Heartland is a volume manufacturer; only 2 model years. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

The family plan: loft plus a real second bedroom, 114 gal of grey, and eight berths - but only 2,100 lb of payload.
