01 What makes it unique
The No Boundaries NB20.4 pairs a versatile Murphy bed with a slide-out for a livable 24-foot couples’ coach. A queen Murphy bed folds up into a sofa by day, turning the front into living space, while a slide-out dinette widens the interior at camp and adds a second convertible berth. An L-shaped kitchen with bar seating, a 12V refrigerator and an air-fryer microwave handles meals, and a rear full bath sits at the back. A standard outdoor kitchen and a 16-foot electric awning extend living space outdoors. Nominal capacity is four. The Murphy bed has to be made up and stowed daily — the trade for an open, sofa-fronted living area and a slide in a sub-25-foot trailer.
At 4,938 pounds unloaded and 24 feet 4 inches, the NB20.4 is a comfortable half-ton tow, with a published 6,438-pound GVWR leaving a healthy 1,500 pounds of cargo capacity. Forest River publishes that GVWR directly (it equals the 4,938-pound unloaded weight plus the 1,500-pound cargo capacity exactly). It steps the fresh and grey tanks up to 40 gallons each (the black stays at 30) for longer stretches between hookups, and rides on a tandem axle. Standard equipment is the mandatory C-Series package: a 12V refrigerator, an air-fryer microwave, a 15,000-BTU air conditioner, an on-demand tankless water heater, a 200-watt solar panel with a 30-amp controller and inverter prep, a central vacuum, a power tongue jack and all-terrain tires with TPMS.
Construction is the No Boundaries laminate recipe — Azdel composite panels over an aluminum frame, a block-foam-insulated aluminum floor, a sealed and heated underbelly with a radiant foil barrier and 12V tank pads, and a fiberglass front cap with LED lighting — the same construction tier as Forest River’s r·pod and a step above the metal-sided value lines. An optional Beast Mode package adds an independent suspension, 400 watts of solar and a 2,000-watt inverter. For a couple that wants the open floor of a Murphy bed, a slide-out living area, bigger tanks and a real awning at an easy half-ton tow weight, the NB20.4 is one of the most flexible compact plans in the line.

03 Forest River No Boundaries floorplan family
Forest River’s No Boundaries (NoBo) is a rugged, adventure-lightweight travel-trailer line built “exceptionally light weight” to tow behind 4- and 6-cylinder vehicles. The NB20.4 on this page is highlighted; the other profiled plans link to their own pages. Profiled here are breadth-spanning floorplans — from the 20-foot front-queen compact to the 33-foot family bunkhouse with rear double bunks — with the rest of the roster catalogued on the line hub and profiled in demand order. Every No Boundaries plan ships with the mandatory C-Series package: a 12V fridge, a 15,000-BTU air conditioner, a tankless water heater, 200 watts of solar, all-terrain tires with TPMS, a standard outdoor kitchen and an electric awning.

Every No Boundaries plan uses superior laminated construction featuring Azdel composite panels over an aluminum frame, with an aluminum-framed floor, block-foam insulation, a sealed and heated underbelly with a radiant foil barrier and 12V tank pads, and a fiberglass front cap with LED lighting — the same construction tier as Forest River’s r·pod, a step above the metal-sided stick-and-tin value lines. The identity is rugged and adventure-focused rather than aerodynamic: every plan ships with the mandatory C-Series package (a 12V refrigerator, an air-fryer microwave, a 15,000-BTU air conditioner, an on-demand tankless water heater, seamless Surf(X) countertops, a 200-watt solar panel with a 30-amp controller and inverter prep, a central vacuum, a power tongue jack, an electric awning with an LED strip, black-glass entry doors, all-terrain tires with TPMS and a standard outdoor kitchen). An optional Beast Mode package adds an independent suspension, a second 200-watt solar panel (400 watts total), a 2,000-watt inverter, a fresh-water filter and a Maxxair vent cover. Lengths, weights and equipment change with options and model year — always confirm against the unit’s own weight sticker. Additional No Boundaries floorplans are catalogued on the line hub.
04 What owners & reviewers report
A Murphy bed and a slide in a compact body
The queen Murphy bed folds to a sofa for open daytime living, and the single slide widens the interior at camp — more livable than a fixed-bed compact, in a sub-25-foot trailer that tows easily.
Bigger 40-gallon tanks and a 16-foot awning
Forty-gallon fresh and grey tanks (vs the 30s on the smaller plans) stretch time between hookups, and the 16-foot electric awning gives real outdoor shade with the standard outdoor kitchen.
Healthy 1,500-lb payload
A 1,500-lb cargo capacity over a 4,938-lb unloaded weight is a comfortable margin for a couple loading full water and gear — more usable load than the lighter compacts.
GVWR is published directly
Forest River lists a 6,438-lb GVWR for this plan (equal to unloaded weight plus cargo capacity), so no derivation is needed — a complete factory weight record.
The Murphy bed must be stowed daily
The bed has to be made up and folded away each morning to use the sofa — a minor daily chore some buyers prefer to avoid with a fixed bed.
Selling price runs below the placard
Dealer MSRP placards run into the low-$50,000s while selling prices commonly land near $34,000–$36,000 (Beast Mode units run higher); the figure shown is dealer-typical selling and is flagged.
05 How it compares
A lighter 21-foot-10 Murphy-bed plan with no slide — the same convertible-bed idea in a smaller, lower-priced body for an even easier tow.
A 25-foot plan with a fixed front queen and a mid-living slide sofa instead of a Murphy bed — no daily bed setup, at a similar weight.
A 29-foot plan with a private front queen bedroom, a tri-fold sofa slide and a walk-through bath — a fixed bedroom and more space at a higher weight.
