01 What makes it unique
Black Series lists the 2027 HQ21 at 7,187 lb dry, a GVWR of 10,000 lb and a tongue weight of 718 lb. Black Series prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 26 ft long. Black Series prints its tanks as 63.4 gal fresh, 26.4 gal grey, 26.4 gal black.
Among the 8 models Black Series lists for 2027 with a published dry weight, it is number 7 from the lightest, in a range from 5,080 lb (HQ12) to 7,247 lb (HQ21 Balcony). Every figure in that comparison is Black Series’, for the same model year.
Every number on this page was read on 5 Nov 2026 from Black Series’ 2027 Spec & Pricing Guide, the maker’s own dated document for model year 2027.
How the HQ21 differs from the other seven Black Series floorplans. Most distinctive first. How these ranks are worked out.

- Tongue weight, 718 lb: third-heaviest of six, between the HQ19 (652 lb) and the TH19 and TH22 (900 lb).
- Length, 26 ft: third-longest of eight, between the HQ19 (25 ft) and the Balcony (27 ft).

- Black tank, 26.4 gal: largest of eight, level with the HQ15 and HQ17; next are the Balcony, HQ12 and two others (26 gal).
- Fresh tank, 63.4 gal: shared with the HQ15 and HQ17; of eight, one smaller and four larger, nearest the TH22 (31.7 gal) and the Balcony, HQ12 and two others (64 gal).
- Sleeping capacity, 4: shared with the Balcony and HQ12; of eight, two smaller and three larger, nearest the HQ15 and HQ19 (3) and the HQ17 (5).

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 (10,000 lb) and the upper loaded tongue estimate (1,500 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 Black Series does not publish for the HQ21
Black Series prints no cargo carrying capacity, tire size, interior height 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
6,847 lb dry and 10,000 lb GVWR, against this model’s 7,187 lb and 10,000 lb.
7,247 lb dry and 10,000 lb GVWR, against this model’s 7,187 lb and 10,000 lb.
