The Ranch Boss STR-650 Series Livestock Trailer is an extra-wide, industrial-grade, full-metal top stock hauler engineered specifically for high-capacity cattle operations, commercial livestock haulers, and severe-duty agricultural fleets.

The "STR-650" designation represents Ranch Boss's premium 6'10" wide (82" interior) full-roof platform. The additional two inches of width over the 6'8" model provides critical shoulder room for mature bulls and large cows to turn around easily. Available in both Gooseneck and Bumper Pull configurations, the STR-650 combines a 10-gauge formed steel body with heavy-duty Dexter torsion axles for maximum structural longevity on highway and pasture runs.

Gooseneck vs. Bumper Pull Structural Frame Configurations

The STR-650 scales its structural framework to match your towing setup and herd payload demands:

• Gooseneck Version: Features a massive 10-inch NeckBoss engineered I-beam neck with a 70" tall riser assembly and a driver-side gooseneck latch release lever. Transferring tongue weight over the tow vehicle's rear axle delivers maximum highway stability and higher payload potential for long-distance market runs.

• Bumper Pull Version: Built around a continuous heavy-duty channel tongue and reinforced A-frame with an adjustable 2-5/16" coupler. Ideal for local farm-to-pasture shuttles, quick hitching, and operators who keep their truck beds equipped with auxiliary fuel tanks or toolboxes.

Extra-Wide 6'10" Interior & Full Metal Roof

The main body structure combines a full steel top sheet with 10-gauge formed steel lower sidewalls, heavy 2" x 2" tubing upper slats, and a 6'10" (82") interior floor width.

• The Benefit: The extra width prevents cattle from jamming hip-to-hip during loading and transport, while 10-gauge steel walls resist violent kicking, body pressure, and horns from adult cattle. The full steel top provides 100% shade and weather protection in summer heat or winter storms.

Heavy-Duty Fabricated 3/16" Plate Crossmembers

Underneath the floor, the frame relies on custom-fabricated 3/16" steel plate crossmember beams spaced on tight 4" centers, backed by 2" x 2" longitudinal angle iron.

• The Benefit: Livestock trailers experience extreme concentrated point loads under hooves. The tight 4" crossmember spacing prevents floor sag, board separation, and structural flex when hauling heavy bulls or densely packed herds.

Center Cut Gate & Heavy Rear Butterfly / Swing Gate Options

The interior livestock compartment comes standard with a heavy-duty center partition gate (with integrated 40" swing gate) and versatile rear doors.

• The Benefit: Allows cattlemen to split livestock into separate weight classes or isolate aggressive animals. The rear loading zone features heavy-duty butterfly doors (or solid swing w/ slider) equipped with commercial slam latches, allowing quick closing to prevent stock from backing out during loading.

4-Foot Side Escape Gate & Diamond Plate Armor

The forward compartment includes a full-height 4-foot passenger/driver-side escape door.

• The Benefit: Gives ranchers a fast, safe exit point after securing center cut gates inside the trailer. The lower front nose is encased in a 36" black diamond plate gravel guard to prevent rock chips from unpaved ranch roads.

6-Stage Baked Powder Coat Finish

The entire steel frame undergoes a thorough shot-blast prep before receiving a heavy-duty powder coat armor.

• The Benefit: Seals the steel against rust, cattle manure corrosion, road salt, and rock impacts. Available in custom finishes including Cloud Grey, Navy Blue, Military Green, and Dragoon Blue.

• Extra 6'10" Shoulder Room: The additional width gives large cattle, mature bulls, and horses extra room to load without scraping sides, reducing stress and injury during transit.

• Maximum Animal Protection: The full steel top isolates cattle from burning direct sunlight, pouring rain, and severe winter wind-chill during long highway drives.

• Heavy-Duty Steel Floor Backbone: Standard light-duty stock trailers use 16"-to-24" crossmember spacing that sags under 1,500 lb. cows. The STR-650’s 4" crossmember spacing provides a rigid floor platform that prevents board warping.

The Ranch Boss STR-650 Livestock Trailer is the premier choice for Commercial Cattle Ranchers, Bull Haulers, Cow-Calf Operators, and Agricultural Fleets. It is built explicitly for operators who demand an extra-wide 6'10", full-top 10-gauge steel stock trailer—in either Gooseneck or Bumper Pull configuration—capable of moving large-frame cattle safely across rough pastures and interstates alike.
