Every number on this page was read on 8 Nov 2026 from KZ’s own 2026 Connect SE floorplan page for the Connect SE C251RLSE, whose heading names the model year 2026.
How the C251RLSE differs from the other nine Connect SE floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.
- Cargo capacity, 1,150 lb: second-smallest of ten, between the C271BHKSE (1,130 lb) and the C211MKSE (1,270 lb).
- Exterior height, 11 ft: second-lowest of ten, between the C221RBSE (10 ft 10 in) and the C201MLSE, C211MKSE and three others (11 ft 2 in).
- Cargo capacity as a share of GVWR, 16.4%: third-smallest of ten, between the C271BHKSE and C312BHKSE (15.1%) and the C301BHKSE (18.8%).
- Tongue weight as a share of dry weight, 13.2%: third-largest of ten, between the C281BHKSE (12.8%) and the C301BHKSE (13.3%).
- Dry weight, 5,850 lb: fifth-heaviest of ten, between the C221RKSE (5,660 lb) and the C271BHKSE (6,370 lb).
- Tongue weight, 770 lb: fifth-heaviest of ten, between the C241BHKSE (710 lb) and the C281BHKSE (860 lb).
- Length, 29 ft 7 in: fifth-longest of ten, between the C241BHKSE (29 ft 1 in) and the C271BHKSE (32 ft 1 in).
- Interior height, 6 ft 6 in: lowest of ten, level with the C221RBSE; next are the C201MLSE, C211MKSE and six others (6 ft 10 in).
- Sleeping capacity, 5: fifth-smallest of ten, between the C201MLSE, C211MKSE and C221RKSE (4) and the C241BHKSE (8).
- GVWR, 7,000 lb: shared with the C221RBSE, C221RKSE and C241BHKSE; of ten, two lower and four higher, nearest the C201MLSE and C211MKSE (6,500 lb) and the C271BHKSE (7,500 lb).
Next to the C221RKSE (2027 page), the nearest lighter floorplan by dry weight, the C251RLSE is 190 lb heavier by dry weight, has 190 lb less cargo capacity, is 2 ft 7 in longer, stands 2 in lower, has 4 in less interior height, has a grey tank 38 gal smaller and sleeps one more; the two publish the same GVWR, fresh 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 (7,000 lb) and the upper loaded tongue estimate (1,050 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). 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 Connect SE C251RLSE
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
5,440 lb dry and 7,000 lb GVWR, against this model’s 5,850 lb and 7,000 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), 32% of the Connect SE C251RLSE’s 1,150 lb cargo capacity, leaving 776 lb (155 lb per rated berth). Across 10 Connect SE floorplans the water share runs 18% to 33%, and 1 gives up more than this one. Nearest on that share: Connect SE C211MKSE at 29% and Connect SE C271BHKSE at 33%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
