01 What makes it unique
Heartland lists the 2023 Bighorn Traveler 39MB at 12,654 lb dry, a GVWR of 16,000 lb and a pin weight of 2,366 lb. Heartland prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 42' 6" long and 13' 3" high. Heartland prints no tank capacity for it.
Among the 7 Bighorn Traveler floorplans Heartland’s 2023 Bighorn Traveler brochure lists with a published dry weight, it is number 5 from the lightest, in a range from 10,803 lb (Bighorn Traveler 32RS) to 13,450 lb (Bighorn Traveler 38FL). 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 Bighorn Traveler brochure, the maker’s own dated document for model year 2023.
How the 39MB differs from the other six Bighorn Traveler floorplans. Most distinctive first. How these ranks are worked out.
- Pin weight as a share of dry weight, 18.7%: smallest of seven; next is the 32RS (18.9%).
- Pin weight, 2,366 lb: second-lightest of seven, between the 32RS (2,047 lb) and the 37DB (2,580 lb).
- Length, 42 ft 6 in: second-longest of seven, between the 37TB (42 ft 5 in) and the 37DB (42 ft 7 in).
- Dry weight, 12,654 lb: third-heaviest of seven, between the 37FB and 37TB (12,115 lb) and the 37DB (12,994 lb).
- Exterior height, 13 ft 3 in: lowest of seven, level with the 32RS and 38FL; next are the 37DB, 37FB and two others (13 ft 4 in).
Next to the 37FB, the nearest lighter floorplan by dry weight, the 39MB is 539 lb heavier by dry weight, has a pin weight 547 lb lighter, is 2 in longer and stands 1 in lower; the two publish the same GVWR.
Next to the 37DB, the nearest heavier floorplan by dry weight, the 39MB is 340 lb lighter by dry weight, has a GVWR 500 lb higher, has a pin weight 214 lb lighter, is 1 in shorter and stands 1 in lower.

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 (16,000 lb) and the upper loaded pin estimate (4,000 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 15–25% of GVWR on the pin, 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 Bighorn Traveler 39MB
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.
05 How it compares
12,115 lb dry and 16,000 lb GVWR, against this model’s 12,654 lb and 16,000 lb.
12,994 lb dry and 15,500 lb GVWR, against this model’s 12,654 lb and 16,000 lb.
