The Freightliner Cascadia Extended Sleeper Truck Cab measures 11 inches long by about 3 inches wide by about 5 inches high (to the top of the cab). The hood and the main cab are made of die cast metal while the extended cab and details are made of plastic. The doors and hood can open revealing nice details and an engine block. These models come in a window box. This is not a toy. Recommended for 15 and up. The Freightliner Cascadia is a heavy-duty semi-trailer truck produced by Freightliner Trucks. The Freightliner Cascadia was designed with fuel efficiency in mind, as well as improving upon several other features including the powertrain offerings, sound mitigation, safety systems, and overall mechanical reliability from its predecessors. It is offered in three basic configurations: Day Cab, Mid-Roof XT, and Raised Roof. The latter two models are sleeper cabs, offered in various lengths, ranging from 48 to 72 inches (Raised Roof models available for 60? or 72? lengths only). The Cascadia was sold chiefly in North America until 2020, when an export, primarily geared towards the Australian and New Zealand markets, was introduced.[1] Before the introduction of the export variant, its place remained occupied by the Freightliner Century (no longer in US production) for export markets.
