A cover system includes a cover, two bail arms, and a fluid circuit. Each bail arm is mounted on a gliding assembly. Each gliding assembly includes a gliding body slidably supported on a vehicle frame, and a cylinder connected to the gliding body and defining first and second ends. The fluid circuit is configured to supply fluid to the first end of the first cylinder and the second end of the second cylinder. A fluid line connects the second end of the first cylinder to the first end of the second cylinder and is configured to direct the fluid between the cylinders such that a flow of the fluid to the first cylinder causes movement of the cylinders, gliding bodies, and bail arms in a first direction, and a flow to the second cylinder causes movement of the cylinders, gliding bodies, and bail arms in a second opposite direction.
