A method and system for supporting trailers carrying mechanical equipment, such as hydraulic fracturing oil and gas equipment are provided. One, two or at least three supports extend from the trailer toward ground and are configured to partially support the trailer when in contact with ground, in addition to any axle groups that exist on the trailer. At least one device configured to absorb, damp, or both absorb and damp vibrations from the mechanical equipment during operation is provided. Each device is operatively coupled to, for example integrated with, a corresponding one of the support structures.
