01 What makes it unique
KZ lists the 2027 Connect SE C312BHKSE at 7,640 lb unloaded (UVW), with a GVWR of 9,000 lb, a cargo carrying capacity of 1,360 lb and a dry hitch weight of 870 lb. Its UVW plus its cargo capacity comes to exactly its GVWR.
It is 36' 7" long and 11' 6" high with the air conditioner, with 45 gal fresh, 38 gal grey and 38 gal black tanks. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank uses roughly 374 lb of the cargo capacity before anything else is loaded.
Among the 8 Connect SE floorplans KZ lists for 2027 with a published weight, it is number 8 by unloaded weight, in a range from 4,910 lb (C201MLSE) to 7,640 lb (C312BHKSE). 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 own floorplan page for the Connect SE C312BHKSE, whose floorplan drawing KZ labels 2027. KZ notes that its UVW reflects a rolling average for the model and that your trailer will vary with optional equipment.
How the C312BHKSE differs from the other seven Connect SE floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 7,640 lb: heaviest of eight; next is the C301BHKSE (7,150 lb).
- GVWR, 9,000 lb: highest of eight; next are the C281BHKSE and C301BHKSE (8,800 lb).
- Length, 36 ft 7 in: longest of eight; next is the C301BHKSE (35 ft).
- Exterior height, 11 ft 6 in: tallest of eight; next are the C281BHKSE and C301BHKSE (11 ft 4 in).
- Dry tongue weight, 870 lb: third-heaviest of eight, between the C281BHKSE (860 lb) and the C271BHKSE (880 lb).
- Dry tongue weight as a share of dry weight, 11.4%: third-smallest of eight, between the C211MKSE (10.9%) and the C221RKSE (11.8%).
- Cargo capacity, 1,360 lb: fourth-smallest of eight, between the C221RKSE (1,340 lb) and the C241BHKSE (1,400 lb).
- Cargo capacity as a share of GVWR, 15.1%: smallest of eight, level with the C271BHKSE; next is the C301BHKSE (18.8%).
- Sleeping capacity, 9: largest of eight, level with the C271BHKSE, C281BHKSE and C301BHKSE; next is the C241BHKSE (8).
Next to the C301BHKSE, the nearest lighter floorplan by dry weight, the C312BHKSE is 490 lb heavier by dry weight, has a GVWR 200 lb higher, has 290 lb less cargo capacity, has a dry tongue weight 80 lb lighter, is 1 ft 7 in longer, stands 2 in taller and has a black tank 38 gal smaller; the two publish the same interior height, fresh tank, grey 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 (9,000 lb) and the upper loaded tongue estimate (1,350 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, 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 C312BHKSE
KZ’s page prints no axle count and no price against this floorplan, so none is given. Nothing is filled from a sibling floorplan, 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
7,150 lb UVW and 8,800 lb GVWR, against this plan’s 7,640 lb and 9,000 lb.
06 Loading it for a trip
A full 45-gallon fresh tank is about 374 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 27% of the C312BHKSE’s 1,360 lb cargo capacity, leaving 986 lb (110 lb per rated berth). Across 8 Connect SE floorplans the water share runs 18% to 33%, and 3 give up more than this one. Nearest on that share: Connect SE C241BHKSE at 27% and Connect SE C221RKSE at 28%. 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
