If you're shopping for a Big Tex dump trailer for sale, the brand name only answers part of the question. Big Tex builds several distinct dump trailer platforms, and each one is engineered around a different combination of weight capacity, lift system, and gate design. Picking the wrong one means paying for capacity you don't need or, worse, buying a trailer that can't handle the loads you actually haul. This guide walks through the Big Tex dump trailer models NC Trailers carries most often, explains what separates a straight-ram lift from a scissor hoist, and gives you a clear way to match a trailer to your tow vehicle and your workload.
Start With the Job, Not the Trailer
Before you compare individual models, think through what you'll be hauling on a normal week. Someone spreading mulch and topsoil around a few residential properties has very different needs than a contractor hauling construction debris off a job site every day. The material you move determines the bed size and gate style that make sense. The frequency and weight of your loads determine the GVWR, or gross vehicle weight rating, you should be shopping for. Big Tex builds trailers across that entire range, from light-duty bumper-pull units for occasional yard work to heavy gooseneck trailers built for daily commercial use.
Big Tex Dump Trailers for Sale: Models and What They're Built For
70SR: Light-Duty and Straightforward
The 70SR is Big Tex's entry point into dump trailers. It carries a 7,000-pound GVWR and roughly 5,270 pounds of payload capacity on a 60-inch-wide bed, and it uses a straight-ram hydraulic lift with double rear doors for dumping. Homeowners and small landscaping operations tend to choose the 70SR for mulch, dirt, and gravel runs that don't require a heavier platform.
10SR: A Medium-Duty Step Up
The 10SR moves up to a 9,990-pound GVWR and an 83-inch bed, still running on a single-ram hydraulic lift but paired with a combo gate that combines barn doors and a spreader gate in one unit. That combo gate is the detail worth noting. It lets you swing the doors fully open to dump a load quickly or lower the spreader gate to control how material comes out, which matters if you're laying gravel or stone rather than just clearing a load.
14LX: A General-Duty Scissor Hoist
The 14LX steps up again to a 14,000-pound GVWR with roughly 10,340 pounds of payload, and it switches lift systems entirely. Instead of a straight ram, it uses a self-contained hydraulic scissor hoist with power up, power down, and gravity down capability. Big Tex's own specifications note that the gravity-down feature lets the 14LX complete more lift cycles over time than a standard power up and down system alone, which matters if you're dumping and resetting the bed dozens of times in a shift. The 14LX also comes with slide-in ramps and a combo gate, making it a practical choice for anyone who needs to haul equipment on some trips and loose material on others.
14GX: Heavy-Duty Gooseneck Capacity
For contractors who need to move the most weight, the 14GX is a gooseneck dump trailer rated for 15,900 pounds GVWR with close to 10,900 pounds of payload on an 83-inch bed. It uses a scissor hoist lift like the 14LX, but the gooseneck pull type shifts more tongue weight onto the tow vehicle's bed rather than the rear bumper, which improves stability at higher GVWR ratings. Dual 12,000-pound drop-leg jacks and a 10-gauge steel floor round out a trailer built for daily commercial hauling rather than occasional use.
Straight-Ram vs. Scissor Hoist: What the Difference Means for You
Big Tex uses two different lift approaches across its dump trailer lineup, and the difference goes beyond how the bed rises. A straight-ram, or single-ram, lift pushes the bed up from one hydraulic cylinder mounted near the front of the trailer. It's a simple, proven design found on the lighter 70SR and 10SR models, and it keeps the trailer's weight and cost down. A scissor hoist, used on the 14LX and 14GX, distributes the lifting force differently and is generally paired with higher payload ratings, since heavier loads put more stress on the lift mechanism during the dump cycle. Neither system is objectively better. The right one depends on how much weight you're rating the trailer for and how many times a day you're cycling the bed.
Gate Styles: Barn Doors, Spreader Gate, or Combo
The 70SR ships with double rear barn doors, which swing fully open so you can back up to a pile or dump zone and let the load go. The 10SR, 14LX, and 14GX all use a combo gate instead, which gives you the barn-door option along with a spreader gate you can lower partway to control the flow of loose material like gravel or stone. If most of your hauling involves dumping a full load in one spot, barn doors alone are enough. If you regularly spread material along a driveway or job site, the combo gate on the larger models earns its keep.
Matching GVWR to Your Tow Vehicle
Every Big Tex dump trailer is only as useful as the tow vehicle pulling it. A 70SR at 7,000 pounds GVWR is within reach of many half-ton trucks and larger SUVs, but a loaded 14GX at nearly 16,000 pounds GVWR needs a three-quarter-ton or one-ton truck with the tow rating, hitch class, and brake controller to match. Check your tow vehicle’s owner’s manual for its rated towing capacity and match that against the trailer's fully loaded weight, not just its empty weight, before you hitch up. Overloading a tow vehicle affects braking and steering in ways that aren't obvious until you're already on the road.
Buying New or Inspecting a Used Big Tex Dump Trailer
New Big Tex dump trailers come with predictable specifications and a factory warranty, which is worth factoring in if you plan to run the trailer hard for years. If you're considering a used unit instead, check the hydraulic pump and cylinder for leaks, inspect the floor and gate hinges for rust or fatigue, and ask about the trailer's service history before you commit. A used dump trailer that has been maintained well can still be a smart purchase, but the hydraulic lift system is the component most likely to show wear first.
