2026 Alliance RV DeltaBH181

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 Note that RVUSA does not publish the air-conditioner count for the Solo plans, so that field is shown as unpublished rather than estimated.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

Fresh water is the single biggest line in this floorplan’s load plan. A full 45-gallon tank is about 39% of the 961-pound cargo capacity — enough that whether you tow with water aboard is a real decision on the BH181 rather than a detail.

The published dry tongue weight of 618 pounds is 13% of the 4,689-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.

Nothing above changes the ceiling. Loaded to its 5,650-pound GVWR the BH181 is towing 961 pounds more than its 4,689-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 45 gallons of fresh against 45 grey and 37 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Of the 7 Delta floorplans profiled here, the BH181 is the lightest by GVWR at 5,650 pounds — the entry point to the line and the one most likely to suit a vehicle already at its limit.

Either side of it in the same line: Delta ML206 is 1,800 pounds heavier at 7,450 lb GVWR.

Against the BH181: the Surveyor Legend 19RBLE is 1 lb lighter; the Ozark 1680BSK is 5 lb heavier. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest travel trailers from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Delta floorplans profiled here run 4,689 to 8,330 pounds dry and 23 to 37 feet of exterior length across 7 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

Every profiled floorplan in this line, with the full weight table, is on the Delta line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 15 of them for the BH181. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: exterior width, interior height, air conditioning, tire size (a tire description is published, a size is not). If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (90%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
