I am looking for an engine diagram for a 2009 Thomas 32' saf-t-liner that has an MBE-900 Detroit Diesel. I am not sure if the online places are legit so looking for some advice or links to PDF's of the build. Thomas indicates that that I need to go through a dealer but the few in my area act like they have no idea what I am asking about. I think a service manual would be perfect.
