Thanks for the reply, I did call Western Star at the Head office, a super nice rep took the information, said to check my e-mail inbox in 10 mins, checked and there was the PDF file for the complete manual.
I was really impressed with the service, super polite, professional and knew what he was doing...
When the time comes to trade the old Star, we will remember this well and they will be first on the list..... at the moment it is working too good
