01 What makes it unique
The BH181 is the lead plan of the new-for-2026 Delta Solo sub-line — Alliance’s lightest and least expensive travel trailer, and the most affordable way into any Alliance towable. It is a compact ‘BH’ bunkhouse sleeping five on a single slide-out in a 22-foot-11 body, at just 4,689 pounds dry with a 618-pound tongue. Delta Solo is the value entry Alliance added below the main Delta line for first-time and budget-focused buyers who still want a family-capable bunkhouse.
The Solo plans share the Delta construction set: a bumper-pull chassis with a walk-on seamless PVC roof, a double-insulated front wall, a heated and enclosed underbelly, 62 cubic feet of drop-frame pass-through storage, Goodyear Endurance tires with Counteract beads on aluminum rims with a spare, a MorRyde Step Above entry, electric auto-leveling and a 10-cubic-foot 12-volt refrigerator. Alliance publishes a 5,650-pound GVWR against the 4,689-pound dry weight, leaving a 961-pound cargo capacity — a tight sub-1,000-pound margin to load carefully — on a 618-pound tongue, with a 45-gallon fresh tank, a 45-gallon grey tank and a 37-gallon black tank. At a starting MSRP around $39,000, the lowest in the whole Alliance range with street pricing below placard, the BH181 is the value-entry Delta Solo bunkhouse for a family towing with a well-rated half-ton or capable SUV. Note that RVUSA does not publish the air-conditioner count for the Solo plans, so that field is shown as unpublished rather than estimated.

Delta is Alliance RV's travel-trailer line — the maker's move into lighter, half-ton-friendly bumper-pull towables, launched in July 2023, alongside a lighter Delta Ultra Lite and a new-for-2026 single-axle Delta Solo sub-line. The 2026 range runs to fifteen plans filed by RVUSA as Delta plus the Solo plans; seven floorplans are profiled here in full and the remaining plans are catalogued from published specifications below. Every Delta rides a bumper-pull tandem-axle chassis with a walk-on seamless PVC roof, a double-insulated front wall, a heated and enclosed underbelly with 12-volt tank heaters, 62 cubic feet of drop-frame pass-through storage, Goodyear Endurance tires with Counteract balancing beads on aluminum rims with a spare, a MorRyde Step Above entry, electric auto-leveling, a 10-cubic-foot 12-volt refrigerator and a 400-watt solar package with a 30-amp MPPT controller and 3,000-watt inverter prep on 50-amp service. Tongue weight, GVWR, dry weight and CCC are published per plan and each plan's dry weight plus CCC equals its GVWR exactly. 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
Cheapest, lightest Alliance towable
At a starting MSRP around $39,000 and 4,689 pounds dry, the BH181 is the most affordable and lightest trailer in the entire Alliance lineup.
Delta Solo — the new-for-2026 value sub-line
Alliance added Delta Solo below the main Delta line as a single-axle-class value entry; BH181 is its lead bunkhouse plan.
Tight cargo margin
A 961-pound CCC is a sub-1,000-pound margin — load water and gear carefully against it, especially with five aboard.
A/C count not published; verify the tow vehicle
RVUSA does not list the air-conditioner count for the Solo plans (shown as unpublished), and you should confirm your half-ton or SUV’s tow rating and hitch class against the loaded weight.
05 How it compares
Jayco’s value Jay Flight SLX — the direct budget family-bunkhouse cross-shop.
Winnebago’s lightweight Micro Minnie — a comparable compact, budget-friendly travel trailer.
The main-line 281BH bunkhouse — longer, heavier, dual entry and more cargo, the next step up from the Solo entry.
