You probably can't believe you just read that subject but it's true. I will be selling my Sierra HD soon. It's going to be replaced with the redesigned '07 model. That will have the 365hp Duramax, 6 speed transmission, sunroof and most of the other options available. It will get the same treatment that I give to most of my other trucks (22s, entertainment system, power mods ect...). I'll be listing it when I get an idea when the new one will be built. This will give people time to plan!
