01 What makes it unique
KZ lists the 2027 Durango Gold G390MLQ at 14,550 lb unloaded (UVW), with a GVWR of 17,500 lb, a cargo carrying capacity of 2,950 lb and a dry pin weight of 2,900 lb. Its UVW plus its cargo capacity comes to exactly its GVWR.
It is 42' 5" long and 13' 6" 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 Gold floorplans KZ lists for 2027 with a published weight, it is number 3 by unloaded weight, in a range from 13,400 lb (G310RLQ) to 15,700 lb (G382MBF). 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 Gold G390MLQ, 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 G390MLQ differs from the other seven Durango Gold floorplans. Most distinctive first. How these ranks are worked out.
- Dry pin weight, 2,900 lb: second-lightest of eight, between the G366FBQ (2,800 lb) and the G382MBF (2,910 lb).
- Dry weight, 14,550 lb: third-lightest of eight, between the G366FBQ (14,100 lb) and the G393MKF (14,650 lb).
- Cargo capacity, 2,950 lb: fourth-largest of eight, between the G359ROQ (2,895 lb) and the G384MSQ (3,095 lb).
- Cargo capacity as a share of GVWR, 16.9%: fourth-largest of eight, between the G393MKF (16.3%) and the G384MSQ (17.2%).
- Dry pin weight as a share of dry weight, 19.9%: shared with the G366FBQ; of eight, one smaller and five larger, nearest the G382MBF (18.5%) and the G388FLS (20.3%).
- GVWR, 17,500 lb: shared with the G366FBQ and G393MKF; of eight, one lower and four higher, nearest the G310RLQ (16,500 lb) and the G359ROQ, G382MBF and two others (17,995 lb).
- Length, 42 ft 5 in: shared with the G382MBF; of eight, four shorter and two longer, nearest the G384MSQ (42 ft 3 in) and the G388FLS and G393MKF (42 ft 11 in).
Next to the G366FBQ, the nearest lighter floorplan by dry weight, the G390MLQ is 450 lb heavier by dry weight, has 450 lb less cargo capacity, has a dry pin weight 100 lb heavier, is 2 ft longer and has a black tank 50 gal smaller; the two publish the same GVWR, exterior height, interior height, fresh tank, grey tank and sleeping capacity.
Next to the G393MKF, the nearest heavier floorplan by dry weight, the G390MLQ is 100 lb lighter by dry weight, has 100 lb more cargo capacity, has a dry pin weight 150 lb lighter, is 6 in shorter and sleeps two fewer; the two publish the same GVWR, 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 (17,500 lb) and the upper loaded pin estimate (4,375 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 G390MLQ
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
14,100 lb UVW and 17,500 lb GVWR, against this plan’s 14,550 lb and 17,500 lb.
14,650 lb UVW and 17,500 lb GVWR, against this plan’s 14,550 lb and 17,500 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), 21% of the G390MLQ’s 2,950 lb cargo capacity, leaving 2,319 lb (580 lb per rated berth). Across 8 Durango Gold floorplans the water share runs 19% to 27%, and 4 give up more than this one. Nearest on that share: Durango Gold G384MSQ at 20% and Durango Gold G359ROQ at 22%. 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 Gold G384MSQ, nearest on the published figures.
