Big Tex 7 x 16 Gooseneck Dump Trailer Solid High Sides
$11,499.00
The Big Tex 7×16 gooseneck dump trailer (model 14GX-16BK6-P4) is a heavy-duty contractor rig built around a 15,900 lb GVWR, 4-foot solid sides, and a hydraulic scissor lift. Gooseneck hitch geometry puts the load weight directly over the rear truck axle for better tow stability and tighter turning than a bumper-pull dump of the same size. The 4-foot sides nearly double the volumetric capacity versus a low-side dump, useful for high-volume mulch, brush, and demolition runs.
Spec highlights for this Big Tex gooseneck dump trailer:
72-inch slide-in ramps, rear barn doors, welded D-rings, tube steel top rail
7-way RV plug, LED lights, tarp kit included
Best for landscape contractors needing high-volume mulch and brush hauls, demolition crews, equipment rental fleets, and 3/4-ton truck operators wanting better tow stability than bumper-pull. Free nationwide delivery on every Big Tex gooseneck dump trailer in our inventory.
Gooseneck hitches mount the trailer in the bed of the tow truck rather than off the rear bumper. That puts the trailer’s tongue weight directly over the truck’s rear axle, which improves stability at highway speeds, tightens the effective turning radius for tight jobsite maneuvering, and increases legal tow capacity beyond what most bumper-pull setups allow. For 7×16 dump trailer applications carrying 10,000+ lb payloads, gooseneck is the right choice.
What Can You Haul?
4 to 5 yards of crushed stone or 6 to 7 yards of mulch (4-ft sides give serious volume)
Loaded mid-frame skid steer plus 2 attachments (ramp-loaded via the 72-inch slide-ins)
Demolition debris from a full kitchen + bath tear-out
10,000 lb of asphalt millings or RAP

Frequently Asked Questions
What truck do I need to tow a gooseneck dump trailer?
You need a pickup with a gooseneck hitch installed in the bed (typically a 3/4-ton or 1-ton truck). The truck’s gooseneck rating must exceed the loaded trailer weight (15,900 lb for this rig). Most modern F-250/2500 trucks handle this; F-350/3500 gives more margin.
Scissor lift vs single cylinder on a gooseneck dump?
Scissor lift tilts the entire bed evenly and reaches a higher dump angle (about 60 degrees vs 45 for single cylinder). For wet aggregate, sticky soil, or large-volume loads where complete clearing matters, scissor is worth the extra cost. Single cylinder is fine for typical landscape and contractor use.
Why 4-foot sides on this Big Tex gooseneck dump trailer?
4-foot sides convert the trailer from weight-limited to volume-limited for low-density loads. For 10,000+ lb payload runs of mulch, brush, leaves, or framing demolition, you fill the trailer by volume long before reaching the GVWR. The 4-foot sides hold a full load without netting or strapping.
