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 Note that RVUSA does not publish the air-conditioner count for the Solo plans, so that field is shown as unpublished rather than estimated.

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). The range starts at the published dry figure, because loaded is never lighter than dry.
03 The Delta floorplan family
Delta is Alliance RV's travel-trailer line — half-ton-friendly bumper-pull towables and a cross-shop against Grand Design's Imagine, Jayco's Jay Flight SLX, Forest River's Salem / Wildwood and Keystone's Passport. Seven floorplans are profiled in full and linked below; the remaining plans, including the new single-axle Delta Solo sub-line, are catalogued and shown muted. The BH181 on this page is highlighted.

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 Notes on this floorplan
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.
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), 39% of the BH181’s 961 lb cargo capacity, leaving 586 lb (117 lb per rated berth). Across 7 Delta floorplans the water share runs 16% to 39%, and this plan’s is the highest. Nearest on that share: Delta 292RL at 23%. 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 Delta ML206, nearest on the published figures. It differs on 7 of the 9 fields both publish (this plan first): length 22 ft 11 in vs 23 ft 11 in; sleeps 5 vs 2; dry weight 4,689 lb vs 5,040 lb; GVWR 5,650 lb vs 7,450 lb; cargo capacity 961 lb vs 2,410 lb; dry hitch weight 618 lb vs 580 lb; black tank 37 gal vs 45 gal. They match on fresh tank and grey tank.

11 NHTSA safety record
NHTSA holds 2 owner complaints against the Delta line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
NHTSA holds no recall campaign against this line, and that is an answer rather than a gap: every query we put to NHTSA for it returned an explicit zero, not an error. A campaign can still be filed under a parent name, so check the VIN of the specific trailer.
Too few reports to show a pattern. 2 complaints have been filed on this line — not enough to say what fails most often. They cover equipment and unknown or other.
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 Delta line page.
