This took me a long while, I built a truck in different models and included a new feature with combining 4x4 and steering in one model.
Standard Cab (with Plow optional)
Dodge T Rex *Google Search Images *
King Ranch (Dually)
Monster Tires (4x4)
*Updated 9/14/15. this project is abandoned due to many errors of the 4x4 not working 100%, transmission with reverse and forward switch doesn't stay together, also rear differential doesn't operate when the truck is slimmed short and lifted.
