01 What makes it unique
The 290KB is where the Zinger roster turns into a family trailer. CrossRoads describes it as a family-friendly plan with two bunks and a queen bedroom, a well-equipped kitchen and a living area with a dinette and entertainment centre, and rates it to sleep eleven in about 34 feet on two slides. Eleven berths at this price is the cheapest double-digit berth count anywhere in the Zinger family. The 2025 published standards for the line list a Super Flex Alpha roof under a limited lifetime warranty, a heated and enclosed underbelly, front diamond plate, pass-through storage, a tankless water heater and an electric awning.
CrossRoads publishes a 9,600-pound GVWR against a 7,062-pound dry weight, leaving 2,538 pounds of cargo capacity and an 842-pound dry tongue. The tank set is 45/39/39 gallons fresh/grey/black — the smallest grey and black tanks on the Zinger roster, which is worth weighing against the eleven-berth rating if you dry-camp with a full crew. The published cargo capacity is 2,538 pounds and the plan is rated to sleep 11. Occupants count against cargo capacity, so a full crew plus gear will use most of it — load to the weight sticker, not to the berth count.
As with the 280RB, the factory marks the 290KB dealer-stock only.

Towing it
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).
03 The Zinger floorplan family
The Zinger is CrossRoads' full-size value travel trailer. It is one of three separate rosters in the Zinger family — the lighter Zinger Lite and the single-axle Zinger Lite Mini carry their own floorplan codes and their own weights, and nothing is shared between them. All nine 2026 Zinger plans are profiled in full and linked below. The 290KB on this page is highlighted.
| Floorplan | Nominal | Sleeps | Notable |
|---|---|---|---|
| 280RB | 32 ft | 6 | One slide, sleeps 6 - layout not published by source |
| 290KB | 33 ft | 11 | Two bunks and a queen bedroom |
| 292RE | 33 ft | 6 | Queen bed, recliners and a fireplace |
| 320FB | 36 ft | 10 | Two slides, sleeps 10 - layout not published by source |
| 328SB | 36 ft | 12 | Two slides, sleeps 12 - layout not published by source |
| 331BH | 37 ft | 12 | Queen bed and a bunkhouse with a flip-up bunk |
| 340BH | 38 ft | 12 | Three slides, sleeps 12 - layout not published by source |
| 340LR | 38 ft | 6 | Two slides, sleeps 6 - layout not published by source |
| 390DB | 43 ft | 8 | King bed, queen bed and a 50-inch TV centre |
Zinger is a cross-shop against Forest River's Salem / Wildwood and Aurora, Prime Time's Avenger, Keystone's Springdale, Coachmen's Catalina and Palomino's Puma. The family runs three separate rosters that share no floorplan codes: this full-size Zinger, the lighter tandem-axle Zinger Lite and the single-axle Zinger Lite Mini. The 2026 factory roster carries nine travel-trailer plans and all nine are profiled here in full. Dry weight, GVWR, cargo capacity and dry tongue weight are published per plan and each plan's dry weight plus cargo capacity equals its GVWR exactly, so the weights below are shown unflagged with no derivation. Dry weight is a factory estimate; real loaded tongue weights run higher — always weigh the loaded trailer and confirm against your vehicle's tow rating and payload.
04 Notes on this floorplan
Eleven berths, and the smallest tanks on the roster
The 39-gallon grey and 39-gallon black tanks are the smallest of the nine 2026 Zinger plans, on the plan with the second-highest berth rating. That combination shortens dry-camping range with a full crew.
Cargo capacity against the berth count
The published cargo capacity is 2,538 pounds and the plan is rated to sleep 11. Occupants count against cargo capacity, so a full crew plus gear will use most of it — load to the weight sticker, not to the berth count.
Dealer stock only
CrossRoads marks the 290KB dealer-stock only, so availability depends on lot inventory rather than a factory order.
Two bunks and a queen bedroom
The factory describes two bunks and a queen bedroom with a dinette and entertainment centre in the living area.
Weigh the loaded trailer
Dry weight is a factory estimate and real loaded tongue weights run above the 842-pound base — weigh the loaded trailer and use a weight-distributing hitch.
05 How it compares
The 280RB — one slide and six berths, 240 pounds lighter dry and about 1,700 dollars less.
The 328SB — twelve berths and three more feet, with larger grey and black tanks.
Keystone's Springdale — the value-bracket family cross-shop from the other volume builder.
06 Loading it for a trip
A full 45-gallon fresh tank is about 375 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 15% of the 290KB’s 2,538 lb cargo capacity, leaving 2,163 lb (197 lb per rated berth). Across 9 Zinger floorplans the water share runs 14% to 29%, and 6 give up more than this one. Nearest on that share: Zinger 280RB at 14% and Zinger 340LR at 15%. 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
Closest sibling: the Zinger 320FB, nearest on the published figures. It differs on 8 of the 9 fields both publish (this plan first): length 33 ft 8 in vs 36 ft 1 in; sleeps 11 vs 10; dry weight 7,062 lb vs 7,695 lb; GVWR 9,600 lb vs 9,800 lb; cargo capacity 2,538 lb vs 2,105 lb; dry hitch weight 842 lb vs 1,000 lb; grey tank 39 gal vs 42 gal; black tank 39 gal vs 42 gal. They match on fresh tank.

11 NHTSA safety record
NHTSA holds 16 recall campaigns and 14 owner complaints against the Zinger line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
What to look at on a used one. Across the 14 complaints filed on this line the most-reported components are equipment (21%), structure (21%) and suspension (21%).
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 Zinger line page.
