A truck including a cab having a front windshield, opposite driver and passenger doors, a cab roof, and a roof fairing disengageably mounted to the cab roof is disclosed herein. The windshield, cab roof and roof fairing are configured so that they present a substantially smooth outer front and side joints between their adjacent outer surfaces, whereby to enhance the aerodynamic qualities of the cab. In the actual embodiment disclosed, the truck is of the conventional class 7 or 8 type as opposed to the cab-over-engine type of truck and is designed so that its opposite driver and passenger doors are located behind the driver and passenger seats rather than directly beside them. At the same time, both the truck\s hood and its windshield wrap around the cab to points adjacent these mid-position doors. The hood is pivotally mounted to the cab and opens up and rearward.
