01 What makes it unique
KZ lists the 2027 Durango D339MLT at 11,770 lb unloaded (UVW), with a GVWR of 13,795 lb, a cargo carrying capacity of 2,025 lb and a dry pin weight of 2,190 lb. Its UVW plus its cargo capacity comes to exactly its GVWR.
It is 37' 6" 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 6 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 D339MLT, 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.
How the D339MLT differs from the other seven Durango floorplans. Most distinctive first. How these ranks are worked out.
- Cargo capacity, 2,025 lb: second-largest of eight, between the D326RLT (2,000 lb) and the D349TBQ (2,615 lb).
- Dry weight, 11,770 lb: third-heaviest of eight, between the D302RLT (11,700 lb) and the D349TBQ (13,380 lb).
- GVWR, 13,795 lb: third-highest of eight, between the D302RLT and D326RLT (13,500 lb) and the D348BHF and D349TBQ (15,995 lb).
- Cargo capacity as a share of GVWR, 14.7%: third-largest of eight, between the D304MKT (14%) and the D326RLT (14.8%).
- Dry pin weight, 2,190 lb: third-lightest of eight, between the D302RLT (2,150 lb) and the D301RLT (2,280 lb).
- Dry pin weight as a share of dry weight, 18.6%: fourth-smallest of eight, between the D302RLT (18.4%) and the D301RLT (20.2%).
- Length, 37 ft 6 in: fourth-longest of eight, between the D302RLT (35 ft 2 in) and the D326RLT (37 ft 7 in).
Next to the D302RLT, the nearest lighter floorplan by dry weight, the D339MLT is 70 lb heavier by dry weight, has a GVWR 295 lb higher, has 225 lb more cargo capacity, has a dry pin weight 40 lb heavier and is 2 ft 4 in longer; the two publish the same exterior height, fresh tank, grey tank, black tank and sleeping capacity.
Next to the D349TBQ, the nearest heavier floorplan by dry weight, the D339MLT is 1,610 lb lighter by dry weight, has a GVWR 2,200 lb lower, has 590 lb less cargo capacity, has a dry pin weight 530 lb lighter, is 5 ft 6 in shorter, has a grey tank 40 gal larger and sleeps four fewer; the two publish the same exterior height, fresh 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 (13,795 lb) and the upper loaded pin estimate (3,449 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 D339MLT
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
11,700 lb UVW and 13,500 lb GVWR, against this plan’s 11,770 lb and 13,795 lb.
13,380 lb UVW and 15,995 lb GVWR, against this plan’s 11,770 lb and 13,795 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), 31% of the D339MLT’s 2,025 lb cargo capacity, leaving 1,394 lb (349 lb per rated berth). Across 8 Durango floorplans the water share runs 24% to 37%, and 6 give up more than this one. Nearest on that share: Durango D349TBQ at 24% and Durango D326RLT at 32%. 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
