01 What makes it unique

KZ lists the 2014 Inferno 3732T at 12,390 lb dry, a GVWR of 16,000 lb, a net carrying capacity of 3,610 lb and a pin weight of 2,610 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.

It is 41' 8" long and 158" 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 6 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 3732T differs from the other eight Inferno floorplans. Most distinctive first. How these ranks are worked out.

  • Pin weight, 2,610 lb: second-heaviest of nine, between the 3010T (2,340 lb) and the 4005T (3,016 lb).
  • Length, 41 ft 8 in: third-longest of nine, between the 3710T (40 ft 7 in) and the 3712T (42 ft 9 in).
  • Dry weight, 12,390 lb: fourth-heaviest of nine, between the 3722T (12,200 lb) and the 3710T (12,415 lb).
  • Cargo capacity, 3,610 lb: fourth-largest of nine, between the 3710T (3,585 lb) and the 3722T (3,800 lb).
  • Cargo capacity as a share of GVWR, 22.6%: fourth-smallest of nine, between the 3710T (22.4%) and the 3010T (23.7%).
  • Pin weight as a share of dry weight, 21.1%: shared with the 3312T; of nine, five smaller and two larger, nearest the 3410T (19.6%) and the 4005T (22.2%).
  • GVWR, 16,000 lb: shared with the 3710T and 3722T; of nine, four lower and two higher, nearest the 3312T and 3410T (14,200 lb) and the 3712T (17,100 lb).
  • Exterior height, 13 ft 2 in: shared with the 3310T; of nine, four lower and three taller, nearest the 3312T, 3410T and two others (13 ft 1 in) and the 3010T, 3710T and 4005T (13 ft 4 in).

Next to the 3722T, the nearest lighter floorplan by dry weight, the 3732T is 190 lb heavier by dry weight, has 190 lb less cargo capacity, has a pin weight 530 lb heavier, is 1 ft 8 in longer and stands 1 in taller; the two publish the same GVWR, interior height and fresh tank.

Next to the 3710T, the nearest heavier floorplan by dry weight, the 3732T is 25 lb lighter by dry weight, has 25 lb more cargo capacity, has a pin weight 300 lb heavier, is 1 ft 1 in longer and stands 2 in lower; the two publish the same GVWR, interior height and fresh tank.

Towing it

Tow rating needed16,000 lb
Published pin weight2,610 lb
Loaded pin weight, rule of thumb2,610–4,000 lb
In-bed fifth-wheel hitch rating needed16,000 lb towed / 4,000 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.

Compares your figures with this page’s published GVWR (16,000 lb) and the upper loaded pin estimate (4,000 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 3732T

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

12,200 lb dry and 16,000 lb GVWR, against this model’s 12,390 lb and 16,000 lb.

Heavier
KZ Inferno 3710T

12,415 lb dry and 16,000 lb GVWR, against this model’s 12,390 lb and 16,000 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), 25% of the Inferno 3732T’s 3,610 lb cargo capacity, leaving 2,697 lb. Across 9 Inferno floorplans the water share runs 19% to 33%, and 5 give up more than this one. Nearest on that share: Inferno 3722T at 24% and Inferno 3710T at 25%. 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 3710T, nearest on the published figures. It differs on 4 of the 6 fields both publish (this plan first): length 41 ft 8 in vs 40 ft 7 in; dry weight 12,390 lb vs 12,415 lb; cargo capacity 3,610 lb vs 3,585 lb; hitch weight 2,610 lb vs 2,310 lb.

09 What this page publishes, and what it does not

10 of the 18 fields this catalogue tracks are published for the Inferno 3732T. Not published: grey tank, black tank, sleeps, slide count, axle count, refrigerator, air conditioning, tire size (a description is published, a size is not).

Sourcing rules: methodology.

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 3732T from 2014. The maker’s own documents for earlier model years also list the 3732T, and that year is printed here: 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.

Source for 2013. Printed in KZ RV’s Inferno brochure (www.kz-rv.com). The document itself prints no model year; KZ RV files it under 2013 in its own brochure folder. Dry weight plus cargo capacity equals the printed GVWR exactly (12,390 + 3,610 = 16,000 lb). Nothing in this record is copied from another model year.

NHTSA record for 2013 Inferno

1 recall campaign filed with NHTSA names the Inferno for model year 2013:

  • 17V749000 (reported 21 Nov 2017): Equipment

No owner complaint filed with NHTSA names the Inferno for model year 2013. NHTSA files recalls and complaints by line and model year, not by floorplan, so a campaign listed here may not affect every Inferno floorplan; the recall notice says which units it covers.
