01 What makes it unique
KZ lists the 2014 Durango GoldRush Discovery at 11,640 lb dry, a GVWR of 14,500 lb, a net carrying capacity of 2,860 lb and a pin weight of 2,130 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 40' 6" long and 12' 11" high. KZ prints its tanks as 67 gal fresh, 57 gal grey, 57 gal black.
Among the 3 Durango GoldRush floorplans KZ’s Durango GoldRush brochure (filed in KZ’s 2014 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 3 from the lightest, in a range from 11,460 lb (Durango GoldRush Klondike) to 11,640 lb (Durango GoldRush Discovery). Every figure in that comparison is KZ’s, for the same model year.
Every number on this page was read on 6 Nov 2026 from KZ’s Durango GoldRush brochure (filed in KZ’s 2014 brochure folder; the brochure prints no year); model year 2014 comes from where the maker files it on its own site, not from the document’s text.
How the Discovery differs from the other two Durango GoldRush 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 (14,500 lb) and the upper loaded pin estimate (3,625 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).

04 Notes on this floorplan
What KZ does not publish for the Durango GoldRush Discovery
KZ prints no sleeping capacity for this model, so none is given. Nothing is filled from a sibling model, 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
11,610 lb dry and 14,500 lb GVWR, against this model’s 11,640 lb and 14,500 lb.
06 Loading it for a trip
A full 67-gallon fresh tank is about 556 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 19% of the Durango GoldRush Discovery’s 2,860 lb cargo capacity, leaving 2,304 lb. Across 3 Durango GoldRush floorplans the water share runs 18% to 19%, and this plan’s is the highest. Nearest on that share: Durango GoldRush Nugget at 19%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
