Not so much for coaches here. You need to check out www.busconversionmagazine.com
where you'll find answers from owners of coaches like yours. Coaches in general are in a universe of their own and require a completely different knowledge set, and MUCH deeper pockets.
School buses are nothing like a coach in design, materials, form or function. Coaches are orders of magnitude more complex and costly when it comes do doing any work on them. You'll be finding that out soon enough. And almost all parts are proprietary to MCI, in your case, and you'll need to deal with them for replacements. You'll be finding out all about that as well.
Have fun and enjoy your new toy. I've owned and driven All coaches and Crown school buses for 50+ years and still do today in commercial service and I know what's in store for you. The BCM site will be much more able to give you REAL and true knowledge from owners who are going through the same things you're soon to be experiencing. They know Coaches and will be able to help you out.
My choice will be an MCI as well when it's time to get a coach for my conversion. I prefer them and find they are the best overall in build quality, handling, ease of repair, and reliability. This is your first lesson. Get yourself an MCI repair manual, and parts book too, you'll need them both. Trust me on this.
