I thought that this one was very cool because one it is a walmart truck and two it is a hybrid. I never would have thought that they would make a hybrid truck.The color to me makes this truck look more environmentally friendly. I think that it is really important for there to be a these kinds of vehicles because of all the carbon monoxide that diesel fuel produces. You will know this if you have ever seen all the black smoke come form the smoke stacks of the truck. I am not a tree huger but I think that it wouldn't hurt to have a few hybrid trucks out on the roads.
