Every number on this page was read on 8 Nov 2026 from KZ’s own 2026 Connect SE floorplan page for the Connect SE C221RBSE, whose heading names the model year 2026.
How the C221RBSE 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.
- Exterior height, 10 ft 10 in: lowest of ten; next is the C251RLSE (11 ft).
- Sleeping capacity, 3: smallest of ten; next are the C201MLSE, C211MKSE and C221RKSE (4).
- Dry weight, 5,440 lb: third-lightest of ten, between the C211MKSE (5,230 lb) and the C241BHKSE (5,600 lb).
- Cargo capacity as a share of GVWR, 22.3%: third-largest of ten, between the C241BHKSE (20%) and the C281BHKSE (23.6%).
- Tongue weight, 620 lb: third-lightest of ten, between the C211MKSE (570 lb) and the C221RKSE (670 lb).
- Cargo capacity, 1,560 lb: fourth-largest of ten, between the C241BHKSE (1,400 lb) and the C201MLSE (1,590 lb).
- Interior height, 6 ft 6 in: lowest of ten, level with the C251RLSE; next are the C201MLSE, C211MKSE and six others (6 ft 10 in).
- Tongue weight as a share of dry weight, 11.4%: shared with the C312BHKSE; of ten, two smaller and six larger, nearest the C211MKSE (10.9%) and the C221RKSE (11.8%).
- Length, 27 ft: shared with the C221RKSE; of ten, two shorter and six longer, nearest the C211MKSE (26 ft 1 in) and the C241BHKSE (29 ft 1 in).
- Grey tank, 76 gal: largest of ten, level with the C221RKSE, C271BHKSE and C281BHKSE; next are the C201MLSE, C211MKSE and four others (38 gal).
- GVWR, 7,000 lb: shared with the C221RKSE, C241BHKSE and C251RLSE; of ten, two lower and four higher, nearest the C201MLSE and C211MKSE (6,500 lb) and the C271BHKSE (7,500 lb).

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).

04 Notes on this floorplan
What KZ does not publish for the Connect SE C221RBSE
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
5,850 lb dry and 7,000 lb GVWR, against this model’s 5,440 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), 24% of the Connect SE C221RBSE’s 1,560 lb cargo capacity, leaving 1,186 lb (396 lb per rated berth). Across 10 Connect SE floorplans the water share runs 18% to 33%, and 6 give up more than this one. Nearest on that share: Connect SE C201MLSE at 23% and Connect SE C241BHKSE at 27%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
