One thing I noticed about Chevys is the box is about 3-4 inches shallower than a ford or dodge. Doesn't sound like much, but a lot of times it makes the difference between being able to close the tonneau cover or not (when you have stuff in the box). Maybe you aren't even thinking about a tonneau cover. They are nice tho. Keep prying eyes out. A Chevy or gmc generally is a few inches lower to the ground also. I have a 05 2500 Chevy and love it has 92k miles engine and tranny still solid.
