01 What makes it unique
Coachmen lists the 2025 Brookstone 370RLLO at 12,730 lb dry, a GVWR of 15,000 lb, a net carrying capacity of 2,270 lb and a pin weight of 2,144 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 41' 4" long and 13' 2" high. Coachmen prints its tanks as 60 gal fresh, 85 gal grey, 45 gal black.
Among the 5 Brookstone floorplans Coachmen’s 2025 Brookstone brochure lists with a published dry weight, it is number 2 from the lightest, in a range from 11,472 lb (Brookstone 290RL) to 13,155 lb (Brookstone 398MBL). Every figure in that comparison is Coachmen’s, for the same model year.
Every number on this page was read on 5 Nov 2026 from Coachmen’s 2025 Brookstone brochure, the maker’s own dated document for model year 2025.

- Grey tank, 85 gal: smallest of five, level with the 398MBL; next are the 290RL, 344FL and 374RK (90 gal).
- GVWR, 15,000 lb: shared with the 344FL; of five, one lower and two higher, nearest the 290RL (14,500 lb) and the 374RK and 398MBL (15,500 lb).
- Cargo capacity as a share of GVWR, 15.1%: shared with the 398MBL; of five, one smaller and two larger, nearest the 344FL (14.7%) and the 374RK (16%).
Next to the 290RL, the nearest lighter floorplan by dry weight, the 370RLLO is 1,258 lb heavier by dry weight, has a GVWR 500 lb higher, has 758 lb less cargo capacity, has a pin weight 322 lb lighter, is 5 ft longer and has a grey tank 5 gal smaller; the two publish the same exterior height, fresh tank and black tank.

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 (15,000 lb) and the upper loaded pin estimate (3,750 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 Coachmen does not publish for the Brookstone 370RLLO
Coachmen prints no sleeping capacity 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
11,472 lb dry and 14,500 lb GVWR, against this model’s 12,730 lb and 15,000 lb.
12,789 lb dry and 15,000 lb GVWR, against this model’s 12,730 lb and 15,000 lb.
06 Loading it for a trip
A full 60-gallon fresh tank is about 498 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 22% of the Brookstone 370RLLO’s 2,270 lb cargo capacity, leaving 1,772 lb. Across 5 Brookstone floorplans the water share runs 16% to 23%, and 1 gives up more than this one. Nearest on that share: Brookstone 398MBL at 21% and Brookstone 344FL at 23%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
