Features & Benefits
20′ × 83″ Car Hauling Deck
The 20′ × 83″ deck gives you plenty of room for full-size vehicles while still providing the versatility to haul tractors, ATVs, side-by-sides, and other equipment.
Big Tex specifically describes the 70CH as a versatile car hauler designed for cars, small tractors, ATVs, and side-by-sides.
That’s a pretty useful list for one trailer.
7,000-Lb GVWR
The 70CH-20 uses two 3,500-lb axles for a 7,000-lb GVWR.
That gives the trailer enough capacity for a wide variety of vehicles and recreational equipment while keeping it in a familiar tandem-axle bumper-pull package.
2′ Dovetail
The rear dovetail provides a gradual transition for loading vehicles and equipment.
Rather than ending the deck abruptly at the rear, the dovetail helps reduce the approach angle as you’re loading—particularly useful for lower-clearance vehicles.
The manufacturer’s Quick Config identifies the DT configuration as a dovetail-equipped 70CH-20. Current 70CH-20BKDT listings identify the dovetail as approximately 2′.
4′ Slide-In Angle Ramps
The 4′ slide-in angle ramps are included in this particular configuration.
They give you a dedicated loading solution for cars, ATVs, tractors, and other equipment without having to carry around homemade ramps or hunt for a suitable loading dock. Big Tex identifies the 4′ slide-in ramp package as an available 70CH option, and the 70CH-20BKDT Quick Config includes it as standard for this configuration.
Removable Teardrop Fenders
The 9″ × 72″ steel teardrop fenders are bolted on and removable.
That gives you flexibility when loading and unloading equipment and makes maintenance or eventual fender replacement easier. Big Tex specifically highlights the removable-fender design as a feature of the 70CH.
Treated-Pine Deck
The treated-pine floor provides a traditional, durable hauling surface with good traction for vehicle and equipment tires.
It’s also straightforward to repair or replace down the road—because eventually somebody will manage to put a tire where a tire probably shouldn’t go.
4″ Channel Fold-Back/Wrap Tongue
The 70CH uses a 4″ channel fold-back/wrap tongue.
That design gives the front of the trailer a clean, integrated structure while keeping the tongue length practical for a bumper-pull car hauler.
Adjustable 2″ Forged Coupler
The standard adjustable 2″ forged coupler allows the trailer to be matched to the appropriate ball height of the tow vehicle.
Big Tex also offers 2-5/16″ forged and stamped coupler options.
Tandem Cambered Axles
Two 3,500-lb premium cambered axles provide the 70CH-20’s 7,000-lb GVWR.
The front axle receives a forward self-adjusting electric brake as standard, with electric brakes on the second axle available as an option.
Stake Pockets Along Both Sides
Stake pockets provide additional flexibility for securing cargo or adding removable side supports when the job calls for them.
That’s particularly handy when the trailer isn’t hauling a vehicle and suddenly gets recruited to haul something completely different.
LED Lighting
LED DOT stop, tail, turn, and clearance lights are standard, along with grommet-mounted lifetime LED lighting and a 7-way RV plug.
