I know the Knight Hauler is a good kit. Expensive though. And you need to buy a separate 4 channel remote. As far as I know, you have to build the whole kit, including the motor. I would research it more. Semi Joe on here builds a lot of 1/14 scale trucks. That's the scale for Tamiya's semi's. Hopefully this helps. Here are some pics. The first one is a stock one. The rest are custom ones. I like the second and third one.
