01 What makes it unique
The 328SB is the first of the roster's three twelve-berth plans and the cheapest of them by about five thousand dollars. CrossRoads rates it to sleep twelve in about 37 feet on two slides, with an 18-foot awning. CrossRoads publishes no floorplan description for this plan anywhere on its site, so no layout claim is made here — the interior arrangement below is not described because it is not published. The slide count, entry count, berth count and every dimension and weight on this page are published figures.
The figure that matters here is the cargo capacity. CrossRoads publishes a 9,740-pound GVWR against an 8,110-pound dry weight, which leaves 1,630 pounds — the second-tightest margin on the roster, on the plan rated for the most people. The published cargo capacity is 1,630 pounds and the plan is rated to sleep 12. 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. The dry tongue is 950 pounds and the tank set is 45/42/42 gallons fresh/grey/black. 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.
The factory roster card rates the 328SB at twelve berths and the RVUSA record rates it at eight. The factory figure is used here, per the standing rule that the manufacturer's own roster wins; both are stated so you can see the spread.

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 328SB on this page is highlighted.

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 What owners & reviewers report
Twelve berths against 1,630 pounds of cargo
The published cargo capacity is 1,630 pounds and the plan is rated to sleep 12. 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.
Sleeps disagreement, factory used
The CrossRoads factory roster card rates the 328SB at twelve berths and the RVUSA record rates it at eight. The factory figure is rendered here and both are stated. Four Zinger plans carry a sleeps disagreement of this kind.
The cheapest twelve-berth Zinger
At about 49,900 dollars it undercuts the 331BH and 340BH, the roster's other twelve-berth plans, by roughly five thousand dollars.
Layout not published
CrossRoads publishes no floorplan description for the 328SB, so no interior arrangement is described here.
Weigh the loaded trailer
Dry weight is a factory estimate and real loaded tongue weights run above the 950-pound base — weigh the loaded trailer and use a weight-distributing hitch.
05 How it compares
The 320FB — two fewer berths, 415 pounds lighter dry and 475 pounds more cargo capacity.
The 340BH — the same twelve berths with an 11,450-pound GVWR and 568 more pounds of cargo capacity.
Prime Time's Avenger — the value-bracket bunkhouse cross-shop.
