2026 Salem FSX 174DBLE

The Salem FSX 174DBLE is the lightest bunkhouse in the value-twin family. At just 3,229 pounds dry it packs a front bed and rear double-size bunks into a 21-foot-8 body with no slide-out, so a wide range of mid-size SUVs and any half-ton can tow it. Nominal sleeping capacity reaches six once the dinette converts. Its twin in the Wildwood FSX 174DBLE is the identical trailer in different décor, so shoppers can pit Salem and Wildwood dealers against each other on price.

FSX is Forest River's value, stick-and-tin line — built on a powder-coated I-beam steel frame with camber, two-inch walls sixteen inches on center, a SuperFlex walk-on roof and a .040 smooth-aluminum front cap with a diamond-plate rock guard. As a Limited Edition Value plan it ships with a string of free upgrades: a 12V power awning, a 13,500-BTU roof air conditioner in place of the base 8,000-BTU side-mount, a full-size spare tire and a larger under-counter refrigerator. A 6-gallon gas water heater and a two-burner LP cooktop handle the basics, and the optional Platinum package adds smooth fiberglass walls with a 200-watt solar panel.

The catch is payload: with a 3,935-pound GVWR the 174DBLE leaves only about 706 pounds of cargo capacity — the tightest in the line — so a family carrying full water, gear and bikes will use it up quickly and should weigh the loaded trailer. For first-time buyers who want real bunks in the smallest, lightest, cheapest package the value twins offer — and the option to shop the identical Wildwood — the 174DBLE is the family's entry bunkhouse, best for those who pack light.

Forest River's Salem FSX and its twin the Wildwood FSX are near-identical lightweight lines — the same stick-and-tin trailers built on the same factory line, differing mainly in graphics and décor and sharing an identical floorplan roster. FSX sits below the laminated Cruise Lite / X-Lite as the value, SUV-towable entry into the family, with a Limited Edition Value tier at the bottom of the price ladder and full-feature ICE and bunkhouse plans above it. The 174DBLE on this page is highlighted; each other profiled plan links to its own page. The line runs to dozens of floorplans across travel trailers, value LE trailers and MAX-Series toy haulers; the highest-demand layouts are detailed here and the rest are catalogued on the line hub.

Water dominates the load plan on this floorplan. Filling the 39-gallon fresh tank consumes about 46% of the 706-pound cargo capacity, which means the 174DBLE is realistically a travel-with-partial-water trailer unless you are heading somewhere with no hookups and are prepared to leave gear behind.

The published dry tongue weight of 435 pounds is 13% of the 3,229-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 3,935-pound GVWR the 174DBLE is towing 706 pounds more than its 3,229-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 39 gallons of fresh against 30 grey and 30 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Of the 4 Salem & Wildwood FSX floorplans profiled here, the 174DBLE is the lightest by GVWR at 3,935 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: Salem & Wildwood FSX 178ICE is 1,645 pounds heavier at 5,580 lb GVWR.

Against the 174DBLE: the Airelume 160 is 10 lb lighter; the Ozark 1620DBLE is 15 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 Salem & Wildwood FSX floorplans profiled here run 3,229 to 4,853 pounds dry and 22 to 30 feet of exterior length across 4 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 Salem & Wildwood FSX line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 17 of them for the 174DBLE. 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: interior height, 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 (88%) 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.

Values on this page carrying an asterisk were derived by arithmetic from published figures, or come from a single source, rather than being printed directly by the manufacturer. The flag travels with the number into the downloadable spec sheet.

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