OK. I am about to purchase a new truck and i dont know which one i should get. My options are The 2007 Freightliner Century Class, The 2007 Kenworth T600, Or the Peterbilt 387. All of them have 475 Kitty Cats in them and are all 13 speed. I like the peety cause it looks nicer than the other ones. Which ones should i Choose. Whats your opinion?
