Equipped with radial tires on braked EZ lube Dexter axles, barn doors, LED lights and many other standard features, the 70 SR, which is one of the smaller Big Tex dump trailers, is still a very capable dump trailer. A GVWR of 7000 lbs, minus the weight of the trailer (roughly 2000 lbs) means that this trailer is ready to take 5000 lbs of material and quickly and conveniently transport it where you need. A single center straight ram piston means that there is no risk of twisting because of uneven cylinder pressure that you would find in a trailer equipped 2 smaller pistons.
