01 What makes it unique
KZ lists the 2027 Durango Gold G388FLS at 15,330 lb unloaded (UVW), with a GVWR of 17,995 lb, a cargo carrying capacity of 2,665 lb and a dry pin weight of 3,110 lb. Its UVW plus its cargo capacity comes to exactly its GVWR.
It is 42' 11" long and 13' 6" high with the air conditioner, with 76 gal fresh, 90 gal grey and 100 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 7 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 G388FLS, 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 G388FLS differs from the other seven Durango Gold floorplans. Most distinctive first. How these ranks are worked out.

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 (17,995 lb) and the upper loaded pin estimate (4,499 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 G388FLS
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
15,100 lb UVW and 17,995 lb GVWR, against this plan’s 15,330 lb and 17,995 lb.
15,700 lb UVW and 17,995 lb GVWR, against this plan’s 15,330 lb and 17,995 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), 24% of the G388FLS’s 2,665 lb cargo capacity, leaving 2,034 lb (339 lb per rated berth). Across 8 Durango Gold floorplans the water share runs 19% to 27%, and 1 gives up more than this one. Nearest on that share: Durango Gold G393MKF at 22% and Durango Gold G382MBF at 27%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
