Your design looks good as others have commented, however I have a pet peeve about text and important graphic elements being cut-off, and your oval logo being chopped off at the front window bothers me. And that makes the overall design look like it as poorly planned and the logo was cut off!
I would reduce the the size of the oval logo so it fits better between the back of the cab and the front window, so it doesn't look cut off, or at least NOT as much as is is now.
Other than the chopped-off logo, it looks pretty cool!
