01 What makes it unique
KZ lists the 2007 Jag 20J at 3,840 lb dry, a GVWR of 6,000 lb, a net carrying capacity of 2,160 lb and a tongue weight of 510 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 21'8" long and 121" high. KZ prints its tanks as 30 gal fresh, 35 gal grey, 35 gal black.
Among the 19 Jag floorplans KZ’s Jag brochure (filed in KZ’s 2007 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 1 from the lightest, in a range from 3,840 lb (Jag 20J) to 8,724 lb (Jag 38J2S). 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 Jag brochure (filed in KZ’s 2007 brochure folder; the brochure prints no year); model year 2007 comes from where the maker files it on its own site, not from the document’s text.
How the 20J differs from the other fourteen Jag travel trailers. Most distinctive first. How these ranks are worked out.
- Dry weight, 3,840 lb: lightest of fifteen; next is the 21JQ (4,286 lb).
- Length, 21 ft 8 in: shortest of fifteen; next is the 21JQ (22 ft 4 in).
- Tongue weight as a share of dry weight, 13.3%: third-largest of fifteen, between the 28JBSS (12.7%) and the 29JB (13.5%).
- Cargo capacity, 2,160 lb: fourth-smallest of fifteen, between the 26JS (2,130 lb) and the 25JQ (2,190 lb).
- Cargo capacity as a share of GVWR, 36%: fourth-largest of eleven, between the 25JS (34.4%) and the 29JSS (36.8%).
- GVWR, 6,000 lb: lowest of fifteen, level with the 21JQ and 24JB; next are the 25JQ, 25JS and three others (7,000 lb).
- Tongue weight, 510 lb: shared with the 21JQ and 25JS; of fifteen, three lighter and nine heavier, nearest the 25JQ (460 lb) and the 29JBS (640 lb).
- Exterior height, 10 ft 1 in: lowest of fifteen, level with the 21JQ, 24JB and three others; next are the 28JBSS, 28JSS and seven others (10 ft 11 in).
- Interior height, 6 ft 6 in: lowest of fifteen, level with the 21JQ, 24JB and three others; next are the 28JBSS, 28JSS and seven others (6 ft 10 in).
Next to the 21JQ, the nearest heavier floorplan by dry weight, the 20J is 446 lb lighter by dry weight, has 554 lb less cargo capacity and is 8 in shorter; the two publish the same GVWR, tongue weight, exterior height, interior height, fresh tank, grey 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 (6,000 lb) and the upper loaded tongue estimate (900 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 KZ does not publish for the Jag 20J
KZ 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
4,286 lb dry and 6,000 lb GVWR, against this model’s 3,840 lb and 6,000 lb.
06 Loading it for a trip
A full 30-gallon fresh tank is about 249 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 12% of the Jag 20J’s 2,160 lb cargo capacity, leaving 1,911 lb. Across 15 Jag travel-trailer floorplans the water share runs 6% to 18%, and 3 give up more than this one. Nearest on that share: Jag 25JQ at 11% and Jag 26JS at 12%. 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 Jag 21JQ, nearest on the published figures. It differs on 3 of the 8 fields both publish (this plan first): length 21 ft 8 in vs 22 ft 4 in; dry weight 3,840 lb vs 4,286 lb; cargo capacity 2,160 lb vs 2,714 lb. They match on GVWR, hitch weight, fresh tank, grey tank and black tank.
| Jag travel-trailer plans | This plan | Position, low to high | Range |
|---|---|---|---|
| GVWR (lb) | 6,000 | 1–3 of 15 | 6,000–10,000 |
| Dry weight (lb) | 3,840 | 1 of 15 | 3,840–8,724 |
| Cargo capacity (lb) | 2,160 | 4 of 15 | 1,380–3,940 |
| Hitch weight (lb) | 510 | 4–6 of 15 | 440–1,110 |
| Length | 21 ft 8 in | 1 of 15 | 21 ft 8 in–38 ft 8 in |
Either side of it by GVWR: Jag 21JQ matches it at 6,000 lb GVWR.

09 What this page publishes, and what it does not
12 of the 18 fields this catalogue tracks are published for the Jag 20J. Not published: sleeps, slide count, axle count, refrigerator, air conditioning, tire size (a description is published, a size is not).
Sourcing rules: methodology.

11 NHTSA safety record
NHTSA holds 3 recall campaigns against the Jag line (a recall and a complaint are not the same thing).
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 Jag line page.
Earlier model years
The record at the top of this page is the 20J from 2007. The maker’s own documents for earlier model years also list the 20J, and that year is printed here: 2006. The figures change from year to year, so check the year on the trailer’s own label. A field a year’s brochure does not print reads “Not published” and is never filled from another year.

Source for 2006. Printed in KZ RV’s Jag brochure (www.kz-rv.com). The document itself prints no model year; KZ RV files it under 2006 in its own brochure folder. Dry weight plus cargo capacity equals the printed GVWR exactly (3,840 + 2,160 = 6,000 lb). Nothing in this record is copied from another model year.
NHTSA record for 2006 Jag
2 recall campaigns filed with NHTSA name the Jag for model year 2006:
No owner complaint filed with NHTSA names the Jag for model year 2006. NHTSA files recalls and complaints by line and model year, not by floorplan, so a campaign listed here may not affect every Jag floorplan; the recall notice says which units it covers.
