Very rare spotting in Pakistan!
This specific truck spotted here is not the high-end level of the Tundra Double Cab category. This is certainly not a CrewMax, which has a full rear seating compartment. Things by which you can tell this isn't even the high-end model in the Double Cab category are the black door handles and side-view mirrors. The high-end models have those covered with chrome.
Oh and by the way, it's not a 5.8L V8, it's a 5.7L V8.
