[Model 57]

Well, I don't have an SRT-8 coming, just an '06 300C, but I am going out of state for it. The dealers here just were too greedy. I will have about a 350 mile drive home.
It is my understanding that you just don't want to keep it at any certain speeds for very long. Keep varying it. I just plan to use the cruise control, and set it at various speeds every once in a while.
Anybody have any ideas on doing this? How long should I plan on staying at a given speed, before changing it? I'm thinking that 10min. at a given speed should be OK. Then change it.
This is something that I should plan out, or plan to do before I make the trip to pick it up. I still have plenty of time, about 3 months before I'll be making this trip. But you don't need to wait till the last minute.
