The Big Tex 3XGN Super Duty Tandem Dual Axle Gooseneck trailer from Big Tex Trailer is a great value in today’s trailer market. Big Tex manufactures their trailers using automated assembly-lines and robotic welding and cutting for precision and quality. Big Tex’s goal is to provide long-lasting service with each trailer. 

Weight Specifics 

The 3XGN has a gross vehicle weight rating (GVWR) of 30,000 pounds. The gross axle weight rating (GAWR) of the 3XGN is 15,000 pounds (for each axle). The Big Tex team has certified engineers and technicians that have designed optimal trailers for maximum payloads and strength. This allows hotshot truckers to push their trailers to the limit with their heavy loads. 


The flatbed on the 3XGN is 102-inches wide. The trailer comes in a variety of lengths. The trailer is available as a 20-feet, 25-feet, 28-feet, and 30-feet. 

The floor of the flatbed has a 2-inch thickness, and it is made with treated pine. Douglas fir is available at the Big Tex facility in Caldwell, Idaho. 

Frame & I-Beam 

The 3XGN has a low profile, pierced frame. The I-Beam on the neck and main frame of the 3xGN is 12-inches. A 12-inch I-Beam is standard in the trailer manufacturing industry. 

Dexter Axles

There are two heavy-duty 15,000-pound axles with dual wheel electric breaks and oil bath hubs. Each axle can hold 15,000 pounds. Dexter Axles is a progressive leader in the automotive manufacturing industry. Dexter Axles are well-crafted and designed to last for years to come.

Adjustable Coupler 

The Big Tex 3XGN has a crank-style square adjustable coupler, and this will help stabilize the trailer. 


The 3XGN has dual two-speed landing gear that is bolted on to the trailer. This allows for an easier and smooth shift from each gear. 


The suspension on the Big Tex 3XGN is a heavy-duty adjustable suspension. Big Tex’s suspension is exclusively by Dexter Axle.  The suspension utilizes a heavy-duty. commercial grade suspension to allow for a better towing and trailer performance.

Self-Adjusting Brakes

The 3XGN has forward self-adjusting brakes. The self-adjusting brakes allow for optimal braking performance no matter how heavy or light the load. 

Dovetail & Ramps 

There is a 5-foot dovetail with 5-foot double-hinged spring assist flip-over ramps on the 3XGN. The ramps make it easier to load and unload your trailer. You can use the dovetail to work on the trailer, as well. 

Spare Tire & Wheel 

The 3XGN has a matching spare tire and wheel. There is also a spare tire mount on the top of the neck. 

Radial Tires

The 3XGN comes standard with radial tires. Radial tires are usually standard in the trailer manufacturing industry. The radial tires are beneficial on hotshot trailers. They distribute the weight of the payload evenly, and it allows for improved stability while a hotshot trucker hauls larger loads. Radial tires also reduce rolling resistance. This will help improve fuel economy and it reduces the wearing on the tires. Radial tires also improve control and it helps with traction in inclement weather.

Tie Down Pockets & Pipe Chain Spools 

The 3XGN has tie down pockets along the sides and are 24-inches in the center. The tie down pockets provides much better anchor points for attaching ropes, cords, and straps. That way hotshot truckers don’t have to tie equipment to the trailer’s side rails or greasy undercarriage.  

There are also 1-1/4-inch pipe chain spools between the tie down pockets. The pipe chain spools are round pieces of pipe added to the stake pockets for several reasons. Pipe chain spools give added support to the rub rails and lesson the problem of bending your rub rails. Pipe chain spools make it easier when you chain your load down.  It is obviously easier to run your chains around a smooth rolled surface rather than a sharp edge of a stake pocket causing the links of the chain to snag and lack in securement.

Side Bed Steps & Handles

The 3XGN comes equipped with two side bed steps and handles. Hotshot truckers will obviously load their trailer, and they will check on their loads. The two side steps (on each side of the trailer) allow hotshot truckers to get on and off the bed of their trailer easier.

Safety Chains & Hook Latches

There are safety chains and safety hook latches on the Big Tex 3XGN. The purpose of safety chains is to retain the connection between the towing vehicle and trailer in the event of separation of the trailer coupling from the ball or the ball from the trailer hitch, long enough to bring the vehicles to a stop. Hopefully, no hotshot trucker has to ever worry about this happening, but it great to know that your trailer is equipped for the event it does.

Rub Rails 

The 3XGN also has 3/8 inch heavy duty rub rails. Rub rails are valuable to your trailer. The rub rails are designed to “rub” against other objects (i.e. walls or highway barricades, etc.). This allows the rub rails to absorb impact and trauma. This protects the trailer from damage. The rub rails also protect the chains, straps, and ropes that are commonly used to secure cargo on the trailer.

Lockable Toolbox 

The Big Tex 3XGN has a lockable toolbox between the gooseneck uprights. The toolbox allows for hotshot truckers to keep tools, straps, chains, and any other equipment they will need safe. 

Torque Tube 

A torque tube is meant to compensate for the weight on the trailer, and Big Tex does make a torque tube on goosenecks that are 28-feet and 30-feet. 

A torque tube will prevent your trailer’s frame from getting frame fatigue and frame flex. If your trailer gets frame fatigue or frame flex, it can start shaking as you are driving down the road. This is dangerous for you and for other drivers.

Complete Break-A-Way Kit 

The Big Tex 3XGN comes standard with a complete breakaway kit and charger. The breakaway kit is designed to bring your trailer safely to a stop by activating its electric brakes if it becomes disconnect while being towed. A rechargeable battery is included so you never have to worry about the breakaway kit not being usable.

Wiring Harness 

The wiring of the Big Tex 3XGN is protected by a modular sealed wiring harness. There are various wires that allow the transfer of power for the lighting, as well as the auxiliary functions of the trailer, such as the electric trailer brake controller, backup lights, or power supply for a winch, or interior trailer lights.

If your gooseneck trailer is not equipped with a preformed wire harness, they can be susceptible to damage. When the wires of the trailer cannot function properly, you cannot use those auxiliary functions. This could be dangerous for you and other drivers on the road. The sealed wiring harness on the 3XGN will protect that wiring.


The Big Tex 3XGN comes with LED lighting. The lighting is protected with a grommet seal.  The LED lighting means your trailer will always be properly lit and it allows for more visibility while traveling. Lighting is required by law.

The 3XGN already comes with the Department of Transportation (DOT) lighting package. Since the lighting is DOT approved, that means the lights are legal throughout the United States and Canada. This gives truckers pace of mind knowing their trailer is up to standards, and they will not have to worry about a fine.


The 25GN’s steel is cleaned to ensure a smooth finish, and then a quality finish is applied to be decorative and protective. The trailer comes in black, red, silver, green, gray, dark blue, and black. Specialty colors and camouflaged are available with additional costs.
