WHICH TOW VEHICLES IT FITS: 19 OF 95

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

Rear-kitchen plan sold only as dealer stock; Heartland never filled in its published height or tank sheet.
