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
~13,277 lbestimated as towed, for 2 people

dry weight 12,060 lb + fresh water (50 gal, full) 417 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 around14,755 lb (10% margin)
GVWR (the sticker maximum)15,000 lb
Tongue weight, loaded~3,061 lb (23%)
Cargo capacity2,892 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 360RD's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

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.

THE READ
