01 What makes it unique
KZ lists the 2027 Sportster X 20X at 7,080 lb unloaded (UVW), with a GVWR of 10,000 lb, a cargo carrying capacity of 2,920 lb and a dry hitch weight of 1,100 lb. Its UVW plus its cargo capacity comes to exactly its GVWR.
It is 26' 9" long and 12' 6" high with the air conditioner, with 94 gal fresh, 38 gal grey and 38 gal black tanks. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank uses roughly 780 lb of the cargo capacity before anything else is loaded.
Among the 7 Sportster X floorplans KZ lists for 2027 with a published weight, it is number 1 by unloaded weight, in a range from 7,080 lb (20X) to 14,620 lb (3914X). Every figure in that comparison is KZ’s, for the same model year.
Every number on this page was read on 5 Nov 2026 from KZ’s own floorplan page for the Sportster X 20X, whose floorplan drawing KZ labels 2027. KZ notes that its UVW reflects a rolling average for the model and that your trailer will vary with optional equipment. KZ marks the floorplan as new.
How the 20X differs from the other six Sportster X floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 7,080 lb: lightest of seven; next is the 22X (7,940 lb).
- GVWR, 10,000 lb: lowest of seven; next is the 22X (12,000 lb).
- Dry tongue weight, 1,100 lb: lightest of seven; next is the 26X (1,140 lb).
- Length, 26 ft 9 in: shortest of seven; next is the 22X (28 ft 5 in).
- Black tank, 38 gal: smallest of seven; next are the 22X, 26X and 33X (40 gal).
- Sleeping capacity, 4: smallest of seven; next are the 22X, 26X and two others (6).
- Cargo capacity, 2,920 lb: second-smallest of seven, between the 3411X (2,440 lb) and the 33X (3,140 lb).
- Cargo capacity as a share of GVWR, 29.2%: second-largest of five, between the 3018X (27.8%) and the 26X (33.1%).
- Dry tongue weight as a share of dry weight, 15.5%: third-smallest of seven, between the 22X (15.2%) and the 33X (16.6%).
- Grey tank, 38 gal: smallest of seven, level with the 26X; next are the 3018X, 3411X and 3914X (50 gal).
Next to the 22X, the nearest heavier floorplan by dry weight, the 20X is 860 lb lighter by dry weight, has a GVWR 2,000 lb lower, has 1,030 lb less cargo capacity, has a dry tongue weight 110 lb lighter, is 1 ft 8 in shorter, has a grey tank 38 gal smaller, has a black tank 2 gal smaller and sleeps two 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 (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). The range starts at the published dry figure, because loaded is never lighter than dry.
03 The Sportster X floorplan family

04 Notes on this floorplan
What KZ does not publish for the 20X
KZ’s page prints no axle count and no price against this floorplan, so none is given. Nothing is filled from a sibling floorplan, 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
7,940 lb UVW and 12,000 lb GVWR, against this plan’s 7,080 lb and 10,000 lb.
06 Loading it for a trip
A full 94-gallon fresh tank is about 780 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 27% of the 20X’s 2,920 lb cargo capacity, leaving 2,140 lb (535 lb per rated berth). Across 7 Sportster X floorplans the water share runs 15% to 34%, and 1 gives up more than this one. Nearest on that share: Sportster X 33X at 25% and Sportster X 3411X at 34%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
07 Where this floorplan sits
Closest sibling: the Sportster X 26X, nearest on the published figures. It differs on 7 of the 9 fields both publish (this plan first): length 26 ft 9 in vs 32 ft 1 in; sleeps 4 vs 6; dry weight 7,080 lb vs 8,530 lb; GVWR 10,000 lb vs 12,750 lb; cargo capacity 2,920 lb vs 4,220 lb; hitch weight 1,100 lb vs 1,140 lb; black tank 38 gal vs 40 gal. They match on fresh tank and grey tank.
