01 What makes it unique
KZ lists the 2027 Durango D304MKT at 11,170 lb unloaded (UVW), with a GVWR of 12,995 lb, a cargo carrying capacity of 1,825 lb and a dry pin weight of 2,380 lb. Its UVW plus its cargo capacity comes to exactly its GVWR.
It is 34' 3" long and 13' 4" high with the air conditioner, with 76 gal fresh, 90 gal grey and 50 gal black tanks. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank uses roughly 631 lb of the cargo capacity before anything else is loaded.
Among the 8 Durango floorplans KZ lists for 2027 with a published weight, it is number 1 by unloaded weight, in a range from 11,170 lb (D304MKT) to 14,200 lb (D348BHF). 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 Durango D304MKT, 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 D304MKT differs from the other seven Durango floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 11,170 lb: lightest of eight; next is the D321RKT (11,200 lb).
- Dry pin weight as a share of dry weight, 21.3%: largest of eight; next is the D321RKT (20.9%).
- Dry pin weight, 2,380 lb: third-heaviest of eight, between the D321RKT (2,340 lb) and the D348BHF (2,580 lb).
- Cargo capacity, 1,825 lb: fourth-largest of eight, between the D302RLT (1,800 lb) and the D326RLT (2,000 lb).
- Cargo capacity as a share of GVWR, 14%: fourth-largest of eight, between the D321RKT (13.8%) and the D339MLT (14.7%).
- Length, 34 ft 3 in: shortest of eight, level with the D301RLT; next is the D321RKT (34 ft 10 in).
- GVWR, 12,995 lb: lowest of eight, level with the D301RLT and D321RKT; next are the D302RLT and D326RLT (13,500 lb).
Next to the D321RKT, the nearest heavier floorplan by dry weight, the D304MKT is 30 lb lighter by dry weight, has 30 lb more cargo capacity, has a dry pin weight 40 lb heavier and is 7 in shorter; the two publish the same GVWR, exterior height, fresh tank, grey tank, black tank and sleeping capacity.

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 (12,995 lb) and the upper loaded pin estimate (3,249 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). The range starts at the published dry figure, because loaded is never lighter than dry.

04 Notes on this floorplan
What KZ does not publish for the D304MKT
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
11,200 lb UVW and 12,995 lb GVWR, against this plan’s 11,170 lb and 12,995 lb.
06 Loading it for a trip
A full 76-gallon fresh tank is about 631 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 35% of the D304MKT’s 1,825 lb cargo capacity, leaving 1,194 lb (299 lb per rated berth). Across 8 Durango floorplans the water share runs 24% to 37%, and 4 give up more than this one. Nearest on that share: Durango D326RLT at 32% and Durango D302RLT at 35%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
07 Where this floorplan sits
Closest sibling: the Durango D321RKT, nearest on the published figures. It differs on 4 of the 9 fields both publish (this plan first): length 34 ft 3 in vs 34 ft 10 in; dry weight 11,170 lb vs 11,200 lb; cargo capacity 1,825 lb vs 1,795 lb; hitch weight 2,380 lb vs 2,340 lb. They match on sleeps, GVWR, fresh tank, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 17 recall campaigns and 10 owner complaints (model years 2005 on) against the Durango line (a recall and a complaint are not the same thing).
What to look at on a used one. Across the 10 complaints filed on this line the most-reported components are structure (50%), tires (20%) and suspension (10%).
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 Durango line page.
