2007 KZJag 21JQ

KZ lists the 2007 Jag 21JQ at 4,286 lb dry, a GVWR of 6,000 lb, a net carrying capacity of 2,714 lb and a tongue weight of 510 lb. KZ’s own figures do not add up — a conflict, stated not resolved: 4,286 lb dry plus 2,714 lb carrying capacity is 7,000 lb, against a printed GVWR of 6,000 lb. All three are shown as KZ prints them and none is corrected; the federal label on the trailer is the one to trust.

It is 22'4" 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 2 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 21JQ differs from the other fourteen Jag travel trailers. Most distinctive first. How these ranks are worked out.

• Dry weight, 4,286 lb: second-lightest of fifteen, between the 20J (3,840 lb) and the 24JB (4,300 lb).
• Length, 22 ft 4 in: second-shortest of fifteen, between the 20J (21 ft 8 in) and the 25JQ (24 ft 9 in).
• GVWR, 6,000 lb: lowest of fifteen, level with the 20J and 24JB; next are the 25JQ, 25JS and three others (7,000 lb).
• Cargo capacity, 2,714 lb: sixth-largest of fifteen, between the 24JB (2,700 lb) and the 33J2S (2,969 lb).
• Tongue weight as a share of dry weight, 11.9%: sixth-largest of fifteen, between the 29JBS (11.4%) and the 38J2S (12.6%).
• Tongue weight, 510 lb: shared with the 20J 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 20J, 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 20J, 24JB and three others; next are the 28JBSS, 28JSS and seven others (6 ft 10 in).

Next to the 20J, the nearest lighter floorplan by dry weight, the 21JQ is 446 lb heavier by dry weight, has 554 lb more cargo capacity and is 8 in longer; the two publish the same GVWR, tongue weight, exterior height, interior height, fresh tank, grey tank and black tank.

Next to the 24JB, the nearest heavier floorplan by dry weight, the 21JQ is 14 lb lighter by dry weight, has 14 lb more cargo capacity, has a tongue weight 60 lb heavier and is 4 ft 6 in shorter; the two publish the same GVWR, exterior height, interior height, fresh tank, grey tank and black tank.

KZ’s Jag brochure (filed in KZ’s 2007 brochure folder; the brochure prints no year) lists 19 Jag floorplans; every one with a printed weight has a page here.

A full 30-gallon fresh tank is about 249 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 9% of the Jag 21JQ’s 2,714 lb cargo capacity, leaving 2,465 lb. Across 15 Jag travel-trailer floorplans the water share runs 6% to 18%, and 9 give up more than this one. Nearest on that share: Jag 33J2S at 8% and Jag 24JB at 9%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).

The record at the top of this page is the 21JQ from 2007. The maker’s own documents for earlier model years also list the 21JQ, 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.
