If you are wondering what happened to my Silverado and Ram projects, here is an update. I received a pair of Silverados from Shapeways and they turned out as planned. I added a bit more material at the axle locations since the wheels wanted to bow outward from only being attached to the body of the truck at the top corner of each wheel. I also found no tires in the package so decided to connect them via a sprue. Now that the file is updated, I will combine both the Chevy and Dodge into a file and print a pair as you see below. I will update again once I have the final prints.
