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
~14,829 lbestimated as towed, for 2 people

dry weight 13,195 lb + fresh water (100 gal, full) 834 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 around16,480 lb (10% margin)
GVWR (the sticker maximum)17,000 lb
Tongue weight, loaded~3,844 lb (26% — high, eats payload)
Cargo capacity3,805 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 335's published weights changed mid-run.

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.

THE READ

Only 3,800 lb of cargo capacity on a 42-ft triple-axle - the numbers are why it was dropped for the 357/364.
