01 What makes it unique
KZ lists the 2024 Sportster 280TH at 8,310 lb dry, a GVWR of 11,500 lb, a net carrying capacity of 3,190 lb and a pin weight of 1,680 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 32' 6" long and 12' 7" high. KZ prints its tanks as 75 gal fresh, 50 gal grey, 50 gal black.
Among the 5 Sportster floorplans KZ’s 2024 Sportster brochure lists with a published dry weight, it is number 3 from the lightest, in a range from 6,840 lb (Sportster 270THR) to 11,070 lb (Sportster 353TH13). Every figure in that comparison is KZ’s, for the same model year.
Every number on this page was read on 6 Nov 2026 from KZ’s 2024 Sportster brochure, the maker’s own dated document for model year 2024.
How the 280TH differs from the other four Sportster floorplans. Most distinctive first. How these ranks are worked out.
- Pin weight, 1,680 lb: lightest of three; next is the 331TH13 (2,300 lb).
- Pin weight as a share of dry weight, 20.2%: smallest of three; next is the 331TH13 (23.5%).
- Cargo capacity, 3,190 lb: second-largest of five, between the 270THR (3,160 lb) and the 331TH13 (3,195 lb).
- Cargo capacity as a share of GVWR, 27.7%: second-largest of five, between the 301THR (25.3%) and the 270THR (31.6%).
- Length, 32 ft 6 in: second-shortest of five, between the 270THR (30 ft 8 in) and the 301THR (35 ft 10 in).
- Black tank, 50 gal: second-largest of five, between the 270THR, 301THR and 331TH13 (32 gal) and the 353TH13 (82 gal).
- Dry weight, 8,310 lb: third-lightest of five, between the 301THR (8,220 lb) and the 331TH13 (9,800 lb).
- GVWR, 11,500 lb: third-lowest of five, between the 301THR (11,000 lb) and the 331TH13 (12,995 lb).
- Sleeping capacity, 7: third-smallest of five, between the 353TH13 (6) and the 301THR and 331TH13 (8).
- Grey tank, 50 gal: shared with the 353TH13; of five, two smaller and one larger, nearest the 270THR and 331TH13 (32 gal) and the 301THR (64 gal).
Next to the 301THR, the nearest lighter floorplan by dry weight, the 280TH is 90 lb heavier by dry weight, has a GVWR 500 lb higher, has 410 lb more cargo capacity, is 3 ft 4 in shorter, stands 4 in taller, has 5 in more interior height, has a grey tank 14 gal smaller, has a black tank 18 gal larger and sleeps one fewer; the two publish the same fresh tank.
Next to the 331TH13, the nearest heavier floorplan by dry weight, the 280TH is 1,490 lb lighter by dry weight, has a GVWR 1,495 lb lower, has 5 lb less cargo capacity, has a pin weight 620 lb lighter, is 6 ft shorter, has a grey tank 18 gal larger, has a black tank 18 gal larger and sleeps one fewer; the two publish the same exterior height, interior height and fresh 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 (11,500 lb) and the upper loaded pin estimate (2,875 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 KZ does not publish for the Sportster 280TH
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
8,220 lb dry and 11,000 lb GVWR, against this model’s 8,310 lb and 11,500 lb.
9,800 lb dry and 12,995 lb GVWR, against this model’s 8,310 lb and 11,500 lb.
06 Loading it for a trip
A full 75-gallon fresh tank is about 622 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 20% of the Sportster 280TH’s 3,190 lb cargo capacity, leaving 2,568 lb (367 lb per rated berth). Across 5 Sportster floorplans the water share runs 19% to 22%, and 3 give up more than this one. Nearest on that share: Sportster 331TH13 at 19% and Sportster 270THR at 20%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

11 NHTSA safety record
NHTSA holds 9 recall campaigns and 6 owner complaints (model years 2005 on) against the Sportster line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 6 complaints have been filed on this line — not enough to say what fails most often. They cover tires, latches/locks/linkages, structure and suspension.
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 Sportster line page.
