Which bus is better all around for service/repairs and replacing? Rear Diesel, front snub nose Diesel or the tilt front end Diesel??

I'm assuming you mean Rear Engine Transit style or Front Engine Transit Style or Conventional.

The Conventional (one with a hood) is the most convenient for engine work. The Front Engine Transit style (without a hood) is the worst for engine work. The Rear Engine Transit style is right behind the conventional. Perhaps a bit more convenient, because you're at ground level.
