Following along with the course, though I am trying a few ideas I had after a complete watching of it to prep. My "brilliant" idea was to add vertical loop cuts before using the knife tool to cut out the wheel wells. So far the biggest difference between me doing that and what Jonathan did was it took me about six times longer to clean up the truck bed section... but I am Ngon free at this point and I am hoping that will pay off when I start breaking out the panels in later lessons.
