Doug, My book is not here so I can't look up your request. However, you could go to your dealers lot and ask to look at the data stored in one of the new Workhorse units computer (Actia instrument panel). That'll give you an idea how high the rpm's have gone on it's delivery run. I think Tom N did a survey of computer data but I can't find the thread. There's also a thread on how to access the information in the Workhorse computer.
Long story short. Some of the MH's have been flogged and some have been driven easy. There are some tough mountain passes between IA and OR and the delivery drivers can't make money going easy. Some "max rpm" figures were close to red line if my memory is correct.
I'd also suggest you get it to your home before the salty highway season and snowstorms up in the passes of Montana/Idaho etc.
HERE is a recent thread on "break-in".
There was another thread recently about renting a car at MSP from ???? (Enterprise??) one way and dropping it at Forest City.
Good luck with the new rig.
