Slidable vehicle crossbar and operating method

A vehicle assembly, comprising:

• a cargo bed of a vehicle;
• a passenger side rail mounted to a passenger side wall assembly of the cargo bed;
• a driver side rail mounted to a driver side wall assembly of the cargo bed;
• a crossbar slidably coupled to the passenger and driver side rails, the crossbar slidable along the passenger and driver side rails between a forward position and a rearward position, the crossbar closer to a cab of the vehicle when the crossbar in the forward position than when the crossbar is in the rearward position;
• a control module and an actuator assembly, the control module configured to control the actuator assembly to reposition the crossbar;
• and
• a radar device configured to scan a load to reveal information identifying the vertically highest point of the load.

A vehicle crossbar operating method, comprising:

• slidably coupling a crossbar to both a passenger side rail and a driver side rail, the passenger side rail mounted to an inner side of a passenger side wall assembly, the driver side rail mounted to an inner side of a driver side wall assembly;
• sliding the crossbar along the passenger and driver side rails between a forward position and a rearward position, the crossbar closer to a cab of a vehicle when the crossbar is in the forward position than when the crossbar is in the rearward position;
• and
• automatically positioning the crossbar based on a load within a cargo bed of the vehicle.
