Hello, Here are my ideas for your logo. The grill shows a predominate "T". Besides simplicity, I wanted to be sure that the logo does not look like a copy of an International truck, but rather have a subtle hint to it. The reason being is that most vehicle manufactures copyright their grills as they do their logos. Too much of a resemblance may put you in a legal issue, because it can be misconstrued as a a direct endorsement.
I also, kept the design to 2 colors for easy reproduction in both print ads as well as screen printing such as caps, t-shirts...
Any part of the logo can be revised, so if you want to change the font, color or add something, not a problem. Your feedback would be greatly appreciated.
