01 What makes it unique
Heartland lists the 2023 Mallard (East Coast edition) M33 at 7,746 lb dry, a GVWR of 9,600 lb and a tongue weight of 702 lb. Heartland prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 36' 8 1/2" long and 11' 6" high. Heartland prints no tank capacity for it.
Among the 11 Mallard floorplans Heartland’s 2023 Mallard East Coast brochure lists with a published dry weight, it is number 10 from the lightest, in a range from 4,598 lb (Mallard (East Coast edition) M210RB) to 8,840 lb (Mallard (East Coast edition) M335). Every figure in that comparison is Heartland’s, for the same model year.
Every number on this page was read on 5 Nov 2026 from Heartland’s 2023 Mallard East Coast brochure, the maker’s own dated document for model year 2023.
How the M33 differs from the other ten Mallard floorplans. Most distinctive first. How these ranks are worked out.

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (9,600 lb) and the upper loaded tongue estimate (1,440 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433).

04 Notes on this floorplan
What Heartland does not publish for the Mallard (East Coast edition) M33
Heartland prints no cargo carrying capacity, tire size, interior height, grey-tank, black-tank for this model, so none is given. Nothing is filled from a sibling model, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). Those figures come from the trailer itself and govern the towing decision.
