01 What makes it unique
Heartland lists the 2023 Road Warrior 375 at 13,304 lb dry, a GVWR of 16,856 lb and a pin weight of 2,856 lb. Heartland prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 40' 10" long and 13' 3" high. Heartland prints no tank capacity for it.
Among the 7 Road Warrior floorplans Heartland’s 2023 Road Warrior brochure lists with a published dry weight, it is number 1 from the lightest, in a range from 13,304 lb (Road Warrior 375) to 15,244 lb (Road Warrior 4275). 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 Road Warrior brochure, the maker’s own dated document for model year 2023.
How the 375 differs from the other six Road Warrior floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 13,304 lb: lightest of seven; next is the 351 (13,450 lb).
- GVWR, 16,856 lb: second-lowest of seven, between the 351 (16,592 lb) and the 391, 3965 and three others (21,000 lb).
- Pin weight, 2,856 lb: second-lightest of seven, between the 351 (2,592 lb) and the 397 (2,920 lb).
- Pin weight as a share of dry weight, 21.5%: third-smallest of seven, between the 397 (20%) and the 391 and 4275 (22.4%).
- Length, 40 ft 10 in: shortest of seven, level with the 351; next are the 397 and 414 (43 ft 10 in).
Next to the 351, the nearest heavier floorplan by dry weight, the 375 is 146 lb lighter by dry weight, has a GVWR 264 lb higher and has a pin weight 264 lb heavier; the two publish the same length and exterior height.

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 (16,856 lb) and the upper loaded pin estimate (4,214 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). The range starts at the published figure, because loaded is never lighter than that.

04 Notes on this floorplan
What Heartland does not publish for the Road Warrior 375
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
13,450 lb dry and 16,592 lb GVWR, against this model’s 13,304 lb and 16,856 lb.
