A retractable cover system includes laterally spaced apart guide rails that each provide a track on either side of an opening. The retractable cover system further includes a cover that has multiple slats that are configured to interlock with one another in a deployed configuration. The slats are slidable in the tracks between first and second positions within the opening. The slats are stacked onto one another in a stowed configuration. The slats include laterally extending profiles that are complementary to one another and are configured to interlock with one another in a deployed configuration. The complementary profiles are configured to decouple from one another in the stowed configuration.

A cargo securing device, a tonneau cover system comprising the cargo securing device, and a method of using the cargo securing device. The tonneau cover system includes a tonneau cover assembly having a tonneau cover and opposing frame rails supporting the tonneau cover on a cargo area of a vehicle. The cargo securing device includes a sleeve and an opening that provides access into the sleeve. The sleeve receives one or more panels of the tonneau cover so that the sleeve surrounds at least a portion of the one or more panels. The cargo securing device can be employed to secure cargo within the cargo area.

A system for modifying the structure of a unibody vehicle includes a vehicle body having a unibody construction and a first module attached to the vehicle body. The first module is removable from the vehicle body and replaceable with a second module having a different size and/or functionality. A rear portion of the first module may be removed from the first module and attached to the second module. The first module may be a stock cargo module, and the second module may be an aftermarket module. The rear portion may be a stock tail tamp and/or sensor module. The rear portion may be removed before or after removing the first module from the vehicle body, and may be attached to the second module before or after attaching the second module to the vehicle body.

A method of operating a tonneau cover and a tailgate of a vehicle, including: transmitting one or more signals to a first control module to open or lower the tailgate; determining a position of the tonneau cover with the first control module or a second control module and transmitting by the first control module and/or the second control module one or more signals to a mechanism associated with the tonneau cover to open the tonneau cover if the tonneau cover is determined by the first control module and/or the second control module to be in a closed position; and then lowering the tailgate.
