Features & Benefits

20′ × 83″ Open Utility Deck

The 20-foot deck gives you plenty of room for equipment, materials, ATVs, side-by-sides, landscaping gear, and general farm or property-maintenance loads. At 83″ wide, you’ve got a generous working platform without stepping up into a larger, heavier trailer class.

7,000-Lb GVWR with Tandem 3,500-Lb Axles

Two 3,500-lb premium cambered axles give the 70PI the capacity and stability expected from a serious tandem-axle utility trailer. Quick-lubricating hubs also make routine maintenance easier.

4′ Three-Way Ramp Gate

This is one of the big reasons to consider this particular configuration. The 4′ ramp gate can serve as a loading ramp, a conventional rear gate, or be folded in when you need the additional clearance for longer cargo. Coil-spring assistance helps make raising and lowering the gate less of a wrestling match.

2″ × 2″ Tube-Top Rail

The 70PI-X uses a 2″ × 2″ square-tube top rail along the open sides. It adds structure to the trailer while giving you a practical sidewall arrangement for everyday hauling.

Four Integrated Tie-Down Pockets

Four integrated tie-down pockets give you convenient attachment points for securing equipment and other cargo. They are built into the trailer rather than leaving you hunting for something suitable to hook onto.

Treated-Pine Floor

The treated-pine deck gives you a traditional utility-trailer hauling surface that works well for equipment, landscaping materials, recreational vehicles, and general cargo.

Adjustable Demco EZ Latch Coupler

The adjustable 2-5/16″ Demco EZ Latch coupler gives you flexibility when matching the trailer to the tow vehicle while making hookup straightforward.

LED Lighting & 7-Way RV Plug

LED DOT lighting provides the required stop, tail, turn, and clearance lighting, while the 7-way RV-style plug provides the standard connection for the trailer’s electrical systems.

Spare-Tire Mount

The SPMT configuration includes the spare-tire mount, giving you a dedicated place to carry a spare rather than letting it roll around in the bed or truck. Big Tex’s Quick Config documentation identifies the 70PI-20XBK4RG configuration with the SPMT option.

Who Is the Big Tex 70PI-20XBK4RG For?

The 70PI-20XBK4RG makes sense for buyers who need one trailer that can handle a bunch of different jobs without moving into a heavier equipment trailer.

It’s a particularly useful fit for:

• Farmers and ranchers
• Landscapers
• Property maintenance companies
• Contractors
• Small equipment operators
• Homeowners with larger hauling needs
• ATV and side-by-side owners
• Golf-cart and recreational vehicle hauling
• Equipment rental and maintenance businesses
• General-purpose farm and property hauling

If your trailer spends as much time hauling equipment as it does hauling materials, the 70PI-X’s combination of an open 83″ deck, pipe-top sides, tandem axles, and three-way ramp gate makes it a versatile choice. Big Tex specifically describes the 70PI-X as being suited for small equipment and agricultural applications.

Frequently Asked Questions

How much can the Big Tex 70PI-20XBK4RG haul?

The Big Tex 70PI-20 has a factory-listed 7,000-lb GVWR and 4,980-lb base cargo capacity. Because options can affect trailer weight, use the certification label on the actual trailer to determine its specific available payload.

How wide is the Big Tex 70PI-20XBK4RG?

The trailer has an 83-inch-wide deck, giving you plenty of room for equipment and recreational vehicles while remaining a conventional bumper-pull utility trailer.

Does the Big Tex 70PI-20XBK4RG have ramps?

Yes. This configuration includes Big Tex’s 4′ Tall 3-Way Ramp Gate with Coil Spring Assist. The gate can function as a loading ramp, rear gate, or fold inward for hauling longer cargo.

Does it have brakes on both axles?

The current standard 70PI specification lists a forward self-adjusting electric brake on the front axle, with electric brakes on the second axle available as an option. Verify the actual trailer’s equipment before purchase if braking on both axles is important for your application.

What size ball does the Big Tex 70PI-20XBK4RG use?

The standard configuration uses an adjustable 2-5/16″ Demco EZ Latch coupler.

What kind of tires does it use?

The standard tire specification is ST205/75 R15 Load Range C.

Is the Big Tex 70PI-20XBK4RG good for ATVs and side-by-sides?

Yes. The 83″ × 20′ deck and rear ramp gate make this configuration well suited to loading recreational equipment such as ATVs and side-by-sides, provided the combined loaded weight remains within the trailer’s rated capacity. Big Tex specifically identifies the 4′ ramp gate as suitable for vehicles including golf carts, ATVs, and side-by-sides.

Safety & Cargo Securement

A trailer is only as useful as the load sitting on it. Always stay within the trailer’s GVWR, individual axle ratings, tire ratings, and tow vehicle limits. Distribute cargo properly, use appropriate tie-down equipment, and inspect the trailer, coupler, safety chains, tires, brakes, and lights before every trip.

To cross-verify that your trailer configuration conforms to modern cargo security standards, review the safety regulations listed on the NATM Website.
