01 What makes it unique
Heartland lists the 2025 Trail Runner 31DB at 6,980 lb dry, a GVWR of 9,608 lb and a hitch weight of 808 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' 11" long and 11' 2" high. Heartland prints no tank capacity for it.
Among the 11 Trail Runner floorplans Heartland’s 2025 Trail Runner brochure lists with a published dry weight, it is number 11 from the lightest, in a range from 3,016 lb (Trail Runner 171BH) to 6,980 lb (Trail Runner 31DB). 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 2025 Trail Runner brochure, the maker’s own dated document for model year 2025.
How the 31DB differs from the other ten Trail Runner floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 6,980 lb: heaviest of eleven; next is the 30RBK (6,960 lb).
- Length, 36 ft 11 in: longest of eleven; next is the 30RBK (35 ft 4 in).
- GVWR, 9,608 lb: second-highest of eleven, between the 30RBK (9,538 lb) and the 27RKS (9,632 lb).
Next to the 30RBK, the nearest lighter floorplan by dry weight, the 31DB is 20 lb heavier by dry weight, has a GVWR 70 lb higher and is 1 ft 7 in longer; the two publish the same exterior height.

04 Notes on this floorplan
What Heartland does not publish for the Trail Runner 31DB
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
6,960 lb dry and 9,538 lb GVWR, against this model’s 6,980 lb and 9,608 lb.
06 Loading it for a trip
No source publishes a tongue weight for the Trail Runner 31DB, so its hitch load has to come from a scale ticket taken with the trailer hitched.
07 Where this floorplan sits
Closest sibling: the Trail Runner 30RBK, nearest on the published figures. It differs on 3 of the 4 fields both publish (this plan first): length 36 ft 11 in vs 35 ft 4 in; dry weight 6,980 lb vs 6,960 lb; GVWR 9,608 lb vs 9,538 lb. They match on sleeps.
| Trail Runner plans | This plan | Position, low to high | Range |

| Dry weight (lb) | 6,980 | 11 of 11 | 3,016–6,980 |

11 NHTSA safety record
NHTSA holds 16 recall campaigns and 8 owner complaints (model years 2005 on) against the Trail Runner line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 8 complaints have been filed on this line — not enough to say what fails most often. They cover electrical system, equipment, structure, suspension and tires.
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Trail Runner line page.
Owner’s manuals
The maker’s own owner’s manual for each model year on this page, linked where the maker publishes it. Each link goes to the maker’s file, labelled as the maker labels it; a year with no manual of its own is not filled from another year.
