1. A vehicle, comprising:
a door panel and a body panel adjacent the door panel;
a roof adjustment assembly, having:
a base located at an upper portion of the vehicle, the base having:
a plurality of guide tubes extending downward from the base, each of the plurality of guide tubes including an outer tube and an inner rod movable between a retracted position and a fully extended position relative to the outer tube,
a foldable cover positioned at least partially above the door panel and extending between a first pair of guide tubes of the plurality of guide tubes, and
a panel cover positioned at least partially above the body panel and extending between a second pair of guide tubes plurality of guide tubes;
a roof coupled to the base; and
a guide tube synchronization system, comprising:
a first motion sensor configured to detect movement of a first inner rod relative to a first outer tube of a first guide tube of the plurality of guide tubes,
a second motion sensor configured to detect movement of a second inner rod relative to a second outer tube of a second guide tube of the plurality of guide tubes,
a controller configured to receive inputs from the first motion sensor and the second motion sensor;
wherein the guide tube synchronization system is configured to:
receive, via the controller, a first signal from the first motion sensor and a second signal from the second motion sensor,
determine, via the controller, a difference between the first signal and the second signal meets a predetermined threshold, and
provide, via the controller, an indication to stop the movement of the first inner rod based on the determined difference between the first signal and the second signal.
