Looking for info on 1999 International Bus
First time posting here -- just joined the site. I recently purchased a semi-converted bus and am excited to start working on it. I'm trying to see if I can track down some of the original documentation (in particular, operator's manual and maybe service manuals if I can find them), but am having trouble knowing exactly what to search for and where. Most importantly, I want to get some good information on general upkeep of the mechanical systems and such (i.e., fluid levels, etc.).
The bus is, from what I can tell, a 1999 International 3000 chassis with an AmTran body. The AmTran manufacturer's plate lists the model as IS2603, which I think may be part of the "Genesis" line of buses? I did manage to find a operator's manual for "International 3000 Bus" on a used book site, but am unsure if that's actually going to help me.
Any advice or thoughts for where to look would be much appreciated. Thanks!
