Paul, I believe that you can get the Spartan Manual from Spartan. I have a '94LY, and it's on the EC2000 chassis. The guy I bought it from had about 2-inches of photocopied Spartan manual for it, which I now have in a binder. It is not complete, but there is a 1-800 number in the manual which you can call for help (my MH is currently at the local Airstream dealer to caulk the roof seams, so I don't have the number handy). The diesel shop I go to for mechanical service seem to have a grasp of this chassis (they service highway coaches, tractors and wast management equipment), and they serviece it without a problem.
