KZ Inferno 4005T (2014) — Specs & Weights

01 What makes it unique

KZ lists the 2014 Inferno 4005T at 13,576 lb dry, a GVWR of 18,500 lb, a net carrying capacity of 4,924 lb and a pin weight of 3,016 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.

It is 44' 5" long and 160" high. KZ prints its tanks as 110 gal fresh.

Among the 9 Inferno floorplans KZ’s Inferno brochure (filed in KZ’s 2014 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 9 from the lightest, in a range from 10,263 lb (Inferno 3310T) to 13,576 lb (Inferno 4005T). 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 Inferno 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 4005T differs from the other eight Inferno floorplans. Most distinctive first. How these ranks are worked out.

Dry weight, 13,576 lb: heaviest of nine; next is the 3712T (12,680 lb).
GVWR, 18,500 lb: highest of nine; next is the 3712T (17,100 lb).
Cargo capacity, 4,924 lb: largest of nine; next is the 3712T (4,420 lb).
Cargo capacity as a share of GVWR, 26.6%: largest of nine; next is the 3712T (25.8%).
Pin weight, 3,016 lb: heaviest of nine; next is the 3732T (2,610 lb).
Length, 44 ft 5 in: longest of nine; next is the 3712T (42 ft 9 in).
Pin weight as a share of dry weight, 22.2%: second-largest of nine, between the 3312T and 3732T (21.1%) and the 3010T (22.4%).
Exterior height, 13 ft 4 in: tallest of nine, level with the 3010T and 3710T; next are the 3310T and 3732T (13 ft 2 in).

Next to the 3712T, the nearest lighter floorplan by dry weight, the 4005T is 896 lb heavier by dry weight, has a GVWR 1,400 lb higher, has 504 lb more cargo capacity, has a pin weight 711 lb heavier, is 1 ft 8 in longer and stands 3 in taller; the two publish the same interior height and fresh tank.

Towing it

Tow rating needed18,500 lb

Published pin weight3,016 lb

Loaded pin weight, rule of thumb3,016–4,625 lb

In-bed fifth-wheel hitch rating needed18,500 lb towed / 4,625 lb pin

Payload check. Budget loaded, not dry: subtract the loaded range, every passenger and the bed and cab load from the payload on your tow vehicle’s door-pillar placard (49 CFR 571.110 S4.3).

Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.

Tow rating (lb) Payload (lb, optional)

Compares your figures with this page’s published GVWR (18,500 lb) and the upper loaded pin estimate (4,625 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). 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 Inferno 4005T

KZ prints no grey-tank, black-tank, 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

Lighter

KZ Inferno 3712T

12,680 lb dry and 17,100 lb GVWR, against this model’s 13,576 lb and 18,500 lb.

06 Loading it for a trip

A full 110-gallon fresh tank is about 913 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 19% of the Inferno 4005T’s 4,924 lb cargo capacity, leaving 4,011 lb. Across 9 Inferno floorplans the water share runs 19% to 33%, and this plan’s is the lowest. Nearest on that share: Inferno 3712T 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 Inferno 3712T, nearest on the published figures. It differs on 5 of the 6 fields both publish (this plan first): length 44 ft 5 in vs 42 ft 9 in; dry weight 13,576 lb vs 12,680 lb; GVWR 18,500 lb vs 17,100 lb; cargo capacity 4,924 lb vs 4,420 lb; hitch weight 3,016 lb vs 2,305 lb. They match on fresh tank.

Inferno plans	This plan	Position, low to high	Range
GVWR (lb)	18,500	9 of 9	13,000–18,500
Dry weight (lb)	13,576	9 of 9	10,263–13,576
Cargo capacity (lb)	4,924	9 of 9	2,737–4,924
Hitch weight (lb)	3,016	9 of 9	1,820–3,016
Length	44 ft 5 in	9 of 9	35 ft 1 in–44 ft 5 in

Either side of it by GVWR: Inferno 3712T is 1,400 lb lighter (17,100 lb GVWR).

11 NHTSA safety record

NHTSA holds 4 recall campaigns and 3 owner complaints (model years 2005 on) against the Inferno line (a recall and a complaint are not the same thing).

Too few reports to show a pattern. 3 complaints have been filed on this line — not enough to say what fails most often. They cover service brakes, hydraulic, structure and suspension.

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 Inferno line page.

Earlier model years

The record at the top of this page is the 4005T from 2014. The maker’s own documents for earlier model years also list the 4005T, and those 4 years are, each from its own brochure printed here: 2010 to 2013. The figures change from year to year, so check the year on the trailer’s own label. A field a year’s brochure does not print reads “Not published” and is never filled from another year.
