An equalized suspension system for a vehicle includes a first trailing arm, a second trailing arm, first and second wheels, and a cushion. The first trailing arm has a lower end pivotally secured to the first wheel, and an upper end pivotally secured to the frame. The second trailing arm has a lower end pivotally secured to the second wheel, a free upper end, and an intermediate portion pivotally secured to the frame. The cushion extends between the lower end of the first trailing arm and the free, upper end of the second trailing arm and serves to transfer and equalize pressures between the first and second wheels. When the first wheel engages an obstacle and moves in a first direction, the cushion forces the second wheel, via the second trailing arm, in a second direction.

What is claimed is: 1. A multi-use vehicle, comprising: a frame having a first side and a second side; a first suspension system disposed on the first side of the frame; and, a second suspension system substantially separate from the first suspension system and disposed on the second side of the frame; wherein each of said first and second suspension systems comprises: a first wheel and a second wheel; a first axle receiving said first wheel and a second axle receiving said second wheel; a first trailing arm having a first end secured to the first axle and a second end pivotally secured to the frame; a second trailing arm having a first end and a second end, said second trailing arm first end being secured to the second axle, said second trailing arm being pivotally secured to the frame at about a midpoint of the second trailing arm, wherein the second end of said second trailing arm is disposed above said frame; and, a cushion extending between the second end of the second trailing arm and the first end of the first trailing arm, said cushion being secured to the first end of the first trailing arm at a location adjacent to said first axle and serving to equalize pressures experienced at said first and second wheels. 2. The multi-use vehicle according to claim 1, wherein said first wheels are mid wheels and said second wheels are rear wheels of said vehicle. 3. The multi-use vehicle according to claim 1, wherein the first and second ends of each said first trailing arm are each respectively a lower end and an upper end, said first wheels each being rotatably secured to the respective first axle secured to the respective lower end and each said upper end being pivotally secured to the frame. 4. The multi-use vehicle according to claim 3, wherein the first and second ends of each said second trailing arm are each respectively a lower end and an upper end, and an intermediate portion disposed between said second trailing arm upper and lower ends comprises the midpoint, said intermediate portion being pivotally secured to said frame. 5. The multi-use vehicle according to claim 4, wherein each said cushion extends between said lower end of each respective said first trailing arm and said upper end of each respective said second trailing arm. 6. The multi-use vehicle according to claim 5, wherein each respective said first trailing arm has a first length and each respective said second trailing arm has a second length, said second length being greater than said first length. 7. The multi-use vehicle according to claim 6, wherein, when each respective said first wheel engages an obstacle, each respective said first trailing arm rotates in a first direction and each respective said second trailing arm is forced in a second, opposite direction. 8. A suspension system for suspending first and second wheels from a frame of a vehicle, comprising: a first axle receiving said first wheel and a second axle receiving said second wheel; a first trailing arm having a lower end and an upper end, said first trailing arm lower end being secured to said first axle, said first trailing arm upper end being pivotally secured to the frame; a second trailing arm having a lower end, an intermediate portion, and an upper end, said second trailing arm lower end being secured to the second wheel and said second trailing arm intermediate portion being secured to the frame, and said second trailing arm upper end being disposed vertically above said frame; and, a cushion having a lower end secured to said first trailing arm lower end and an upper end secured to said second trailing arm upper end, said cushion serving to transfer and equalize pressures experienced by said first and second wheels. 9. The suspension system according to claim 8, wherein said first trailing arm has a first length and said second trailing arm has a second length, said second length being greater than said first length. 10. The suspension system according to claim 9, wherein, when said first wheel engages an obstacle, said first trailing arm rotates in a first direction and said second trailing arm is forced in a second, opposite direction. 11. The suspension system according to claim 9, wherein, when one of said first and second wheels moves in a first direction the other of said first and second wheels moves in a second direction.
