01 What makes it unique
KZ lists the 2018 Durango 2500 D325RLT at 10,290 lb dry, a GVWR of 13,000 lb, a net carrying capacity of 2,710 lb and a pin weight of 2,100 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 36' 8" long and 12' 9" high. KZ prints its tanks as 67 gal fresh, 57 gal grey, 57 gal black.
Among the 7 Durango 2500 floorplans KZ’s Durango 2500 brochure (filed in KZ’s 2018 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 2 from the lightest, in a range from 10,100 lb (Durango 2500 D315RKD) to 12,440 lb (Durango 2500 D347BHF). 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 2500 brochure (filed in KZ’s 2018 brochure folder; the brochure prints no year); model year 2018 comes from where the maker files it on its own site, not from the document’s text.
How the D325RLT differs from the other six Durango 2500 floorplans. Most distinctive first. How these ranks are worked out.
- Cargo capacity as a share of GVWR, 20.8%: largest of seven; next is the D318RLT (20.3%).
- Pin weight as a share of dry weight, 20.4%: largest of seven; next is the D318RLT (19.6%).
- Dry weight, 10,290 lb: second-lightest of seven, between the D315RKD (10,100 lb) and the D318RLT (10,360 lb).
- Pin weight, 2,100 lb: third-heaviest of seven, between the D337RET (2,050 lb) and the D347BHF (2,110 lb).
- Length, 36 ft 8 in: fourth-shortest of seven, between the D337RET (35 ft 4 in) and the D340FLT (38 ft 11 in).
- Cargo capacity, 2,710 lb: largest of seven, level with the D343MBQ; next is the D318RLT (2,640 lb).
- Exterior height, 12 ft 9 in: shared with the D318RLT and D340FLT; of seven, one lower and three taller, nearest the D315RKD (12 ft 8 in) and the D337RET, D343MBQ and D347BHF (12 ft 10 in).
- GVWR, 13,000 lb: shared with the D318RLT and D340FLT; of seven, two lower and two higher, nearest the D315RKD and D337RET (12,500 lb) and the D343MBQ and D347BHF (14,500 lb).

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 (13,000 lb) and the upper loaded pin estimate (3,250 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 figure, because loaded is never lighter than that.

04 Notes on this floorplan
What KZ does not publish for the Durango 2500 D325RLT
KZ prints no interior height, 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
10,100 lb dry and 12,500 lb GVWR, against this model’s 10,290 lb and 13,000 lb.
10,360 lb dry and 13,000 lb GVWR, against this model’s 10,290 lb and 13,000 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), 21% of the Durango 2500 D325RLT’s 2,710 lb cargo capacity, leaving 2,154 lb. Across 7 Durango 2500 floorplans the water share runs 21% to 32%, and 5 give up more than this one. Nearest on that share: Durango 2500 D343MBQ at 21% and Durango 2500 D318RLT at 21%. 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 2500 D318RLT, nearest on the published figures.
