Especially when compared with a dump truck, a dump trailer is simply lighter. It can be driven onto a sensitive landscape like a lawn or over a walkway to reach hard-to-access areas without causing damage. Low impact is especially true when compared to a roll-off dumpster for waste removal. The rubber tires of a dump trailer don’t scar an asphalt driveway or tear up a lawn like the loading and unloading of a roll-off dumpster.http://www.tongyatrailer.com/t....ruck-trailer-semi-tr
