I have a big bonus coming for you R-Series owners soon!  I have taken the time and expense to convert both the MT-97 Parts Manual and the CTS-11/12 Service Manual for the R-Series trucks to PDF format and will make them available as a complete set on this site shortly.  They will be available for your information and I will be putting security restrictions in the files so that they cannot be redistributed.  I have to be careful because of copyright laws, but as far as I can tell, as long as I am not selling them and I ask you not to sell them, we should be OK.  The security restrictions I add to the files should allow you to print them only, and I am doing this for Susan's and my protection, while at the same time; yours.  This way we can ALL benefit from this vast wealth of information.  Check back in a few days for more :-)
