You are wrong Seskom, he did not copy anything. Look closer to the signature and you'll see the difference.
He wanted exactly that picture with that truck, RS Haul is a company in San Andreas(and some other GTA games I think), therefore you can picture-Google on RS Haul and you will get the logo. As you got the logo, obviously you put it on the truck and nowhere else. He wanted his name and his rank above the name - they both wrote the name in that order he wanted it. The logos aren't put in the same structure on the truck, the background is totally not the same, neither is the font.
So no. He didn't copy a damn shit from Traser.
