Every number on this page was read on 8 Nov 2026 from KZ’s own 2026 Durango floorplan page for the Durango D333RLT, whose heading names the model year 2026.
How the D333RLT differs from the other ten Durango floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.
- Exterior height, 12 ft 8 in: second-lowest of eleven, between the D281RKD (12 ft 6 in) and the D341RPT (12 ft 11 in).
- Cargo capacity, 2,100 lb: third-largest of eleven, between the D341RPT (2,080 lb) and the D349TBQ (2,615 lb).
- Cargo capacity as a share of GVWR, 15.3%: third-largest of eleven, between the D326RLT (14.8%) and the D349TBQ (16.3%).
- Length, 37 ft 10 in: fourth-longest of eleven, between the D326RLT (37 ft 7 in) and the D341RPT (37 ft 11 in).
- GVWR, 13,700 lb: fifth-highest of eleven, between the D302RLT and D326RLT (13,500 lb) and the D339MLT (13,795 lb).
- Dry weight, 11,600 lb: sixth-lightest of eleven, between the D326RLT (11,500 lb) and the D302RLT (11,700 lb).
- Pin weight, 2,260 lb: sixth-lightest of eleven, between the D339MLT (2,190 lb) and the D301RLT (2,280 lb).
- Pin weight as a share of dry weight, 19.5%: sixth-smallest of eleven, between the D339MLT (18.6%) and the D301RLT (20.2%).
- Grey tank, 50 gal: smallest of eleven, level with the D348BHF and D349TBQ; next are the D281RKD, D301RLT and six others (90 gal).
Next to the D326RLT (2027 page), the nearest lighter floorplan by dry weight, the D333RLT is 100 lb heavier by dry weight, has a GVWR 200 lb higher, has 100 lb more cargo capacity, is 3 in longer, stands 8 in lower, has a grey tank 40 gal smaller and sleeps two fewer; the two publish the same fresh tank and black tank.
Next to the D302RLT (2027 page), the nearest heavier floorplan by dry weight, the D333RLT is 100 lb lighter by dry weight, has a GVWR 200 lb higher, has 300 lb more cargo capacity, is 2 ft 8 in longer, stands 8 in lower and has a grey tank 40 gal smaller; the two publish the same fresh tank, black tank and sleeping capacity.

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 (13,700 lb) and the upper loaded pin estimate (3,425 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 D333RLT
KZ prints no interior height 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
The weight label every RV trailer carries by law (49 CFR 571.110 and 571.120) governs the towing decision, not this page.
05 How it compares
9,910 lb dry and 12,995 lb GVWR, against this model’s 11,600 lb and 13,700 lb.
12,420 lb dry and 14,500 lb GVWR, against this model’s 11,600 lb and 13,700 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), 30% of the Durango D333RLT’s 2,100 lb cargo capacity, leaving 1,469 lb (367 lb per rated berth).

Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
