01 What makes it unique
KZ lists the 2018 Durango 1500 D251RLT at 7,810 lb dry, a GVWR of 10,000 lb, a net carrying capacity of 2,190 lb and a pin weight of 1,420 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 28' 2" long and 12' 1" high. KZ prints its tanks as 61 gal fresh, 57 gal grey, 57 gal black.
Among the 9 Durango 1500 floorplans KZ’s Durango 1500 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 7,620 lb (Durango 1500 D250RKS) to 9,430 lb (Durango 1500 D292BHT). 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 1500 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 D251RLT differs from the other eight Durango 1500 floorplans. Most distinctive first. How these ranks are worked out.
- Length, 28 ft 2 in: shortest of nine; next is the D259RDD (29 ft 11 in).
- Dry weight, 7,810 lb: second-lightest of nine, between the D250RKS (7,620 lb) and the D259RDD (7,840 lb).
- Cargo capacity as a share of GVWR, 21.9%: second-largest of nine, between the D281RLT (21.8%) and the D250RKS (23.8%).
- Cargo capacity, 2,190 lb: third-largest of nine, between the D259RDD (2,160 lb) and the D250RKS (2,380 lb).
- Pin weight as a share of dry weight, 18.2%: third-largest of nine, between the D284RLT (18.1%) and the D250RKS (18.9%).
- Pin weight, 1,420 lb: fourth-lightest of nine, between the D292BHT (1,410 lb) and the D250RKS (1,440 lb).
- GVWR, 10,000 lb: lowest of nine, level with the D250RKS and D259RDD; next are the D270RLD, D277RLT and two others (10,500 lb).
- Exterior height, 12 ft 1 in: tallest of nine, level with the D250RKS, D270RLD and D284RLT; next are the D259RDD, D277RLT and three others (12 ft).
Next to the D250RKS, the nearest lighter floorplan by dry weight, the D251RLT is 190 lb heavier by dry weight, has 190 lb less cargo capacity, has a pin weight 20 lb lighter, is 2 ft shorter, has a fresh tank 6 gal larger and has a grey tank 40 gal smaller; the two publish the same GVWR, exterior height and black tank.
Next to the D259RDD, the nearest heavier floorplan by dry weight, the D251RLT is 30 lb lighter by dry weight, has 30 lb more cargo capacity, has a pin weight 320 lb heavier, is 1 ft 9 in shorter and stands 1 in taller; the two publish the same GVWR, 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 (10,000 lb) and the upper loaded pin estimate (2,500 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 1500 D251RLT
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
7,620 lb dry and 10,000 lb GVWR, against this model’s 7,810 lb and 10,000 lb.
7,840 lb dry and 10,000 lb GVWR, against this model’s 7,810 lb and 10,000 lb.
06 Loading it for a trip
A full 61-gallon fresh tank is about 506 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 23% of the Durango 1500 D251RLT’s 2,190 lb cargo capacity, leaving 1,684 lb. Across 9 Durango 1500 floorplans the water share runs 19% to 27%, and 6 give up more than this one. Nearest on that share: Durango 1500 D281RLT at 20% and Durango 1500 D259RDD at 23%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
07 Where this floorplan sits
Closest sibling: the Durango 1500 D259RDD, nearest on the published figures. It differs on 4 of the 8 fields both publish (this plan first): length 28 ft 2 in vs 29 ft 11 in; dry weight 7,810 lb vs 7,840 lb; cargo capacity 2,190 lb vs 2,160 lb; hitch weight 1,420 lb vs 1,100 lb. They match on GVWR, fresh tank, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 1 recall campaign and 1 owner complaint (model years 2005 on) against the Durango 1500 line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 1 complaint has been filed on this line — not enough to say what fails most often. It covers equipment.
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Durango 1500 line page.
