Check out this great infographic from B&W Trailer Hitches timelining the evolution of trucks from the 1900s to 2012. It shows the different models and body shapes over the decades with information on horsepower and engine size for each model. It includes Ford, Chevy, Dodge and Toyota trucks as well as interesting information on towing capacities and the amount of parts of these trucks that are actually made here in the U.S.It reads better from the actual site it's from: http://www.turnoverball.com/blogs/2012/07/modern-truck-0
This is something very interesting you have shared. Beautiful vintage trucks !!
