01 What makes it unique
The Access 18DBH is the family answer at the bottom of the range: a private-feeling front queen, a rear corner bathroom, a set of bunk beds and a pass-through storage bay, sleeping five in a 22-foot-6 trailer that a half-ton tows without thinking. It undercuts every tandem plan on price and weight.
The value build carries through — NXG engineered steel frame, Tuff-Coat metal exterior, one-piece TPO roof, enclosed radiant-foil underbelly, a single 5,100-pound axle on 15-inch Load Range E tires, an 8,000-BTU roof A/C, an 18,000-BTU furnace and a 6-gallon DSI water heater — and the published dry weight plus payload equals the 5,100-pound GVWR exactly.
At 3,850 pounds dry with a 550-pound tongue, the 18DBH is easy to tow and, at an MSRP just above $22,000, the second-cheapest Access. Its 1,250 pounds of payload asks for disciplined loading once five people's gear is aboard, but for a family that wants a genuine bunkhouse in the lightest, most affordable Winnebago trailer, it is the value pick of the single-axle plans.

03 Access floorplan family
Winnebago's Access line — the value-priced range of the towable lineup: fourteen 2026 travel trailers spanning compact single-axle plans rated to 5,100 pounds up to the 37-foot-11 flagship on its own 10,400-pound chassis. The 18DBH on this page is highlighted; every 2026 plan links to its own profiled page.

The Access splits into two build classes. The four single-axle plans (15- and 18-series) are rated to a 5,100-pound GVWR on one 5,100-pound axle, with an 8,000-BTU roof A/C, an 18,000-BTU furnace and a 6-gallon DSI water heater. The ten tandem plans carry an 8,800-pound GVWR on 4,400-pound axles — the 32BR uniquely on 5,200-pound axles for 10,400 pounds — and add a 13,500-BTU ducted A/C, a 30,000-BTU furnace, a 60,000-BTU tankless water heater, a 10-cubic-foot refrigerator and a 2-inch accessory receiver. On every plan the published dry weight plus payload equals the GVWR exactly. Figures are RVUSA structured records cross-checked against Winnebago's factory specification table; tongue weights, awning lengths, axle ratings and dual-grey-tank capacities are factory figures. Always confirm against the unit's weight sticker before towing.
04 What owners & reviewers report
A bunkhouse a half-ton tows easily
Five berths at 3,850 lb dry and a 550-lb tongue — family space without a big-truck requirement.
Pass-through storage
A front pass-through bay swallows chairs, hoses and outdoor gear that would otherwise ride inside.
Second-lowest price in the line
At just over $22,000 MSRP the 18DBH is beaten only by the 15BH — the value family plan.
Mind the loaded weight
1,250 lb of payload goes quickly with five aboard; weigh the rig loaded and watch the single axle's rating.
05 How it compares
The same shell with a rear kitchen instead of bunks — for couples rather than families.
The value tandem bunkhouse — a slide, an outdoor kitchen and 3,100 lb of payload.
The single-axle Thor-side rivals — compare bunk layouts, payload and build.
