I have worked on every type of bus out there including Type 'A' buses on van cut-away chassis, Type 'B' buses on P-30/Freightliner rail chassis, Type 'C' buses on conventional truck chassis, and Type 'D' buses with engines in front, in the middle, in the rear, on OEM vendor supplied chassis (GMC, IHC, Oshkosh, National, Spartan), and integrated chassis. I have worked on commercial buses, school buses, transit buses, and highway coaches. Of them all, the Crown and Gillig buses with the engines mounted in the middle are the easiest on which to work. Once the side rail is removed there is nothing to get in the way of getting to the engine. The only things that are not accessible from down below are the starter and water pump on the DD 6-71 engines. There is nothing on the Cummins that needs the floor boards taken up to be able to reach.
So what I am saying is yes it costs less to work on a mid-mount Crown or Gillig because you do not have to pay for a lot of time for a technician to burrow down through rat nests of wires and hoses to reach the engine. Except for a few of the late '80's vintage Crowns all were totally mechanical. And the later models that had electronics had DDEC/ATEC I/II which were pretty simple.
Changing the water pump on any Crown does not require the removal of the radiator.
Setting the rack, changing injectors, changing the pump, changing the turbo, changing the thermostats, etc. can all be done without spending time digging down through stuff to get to what needs fixing.
Crowns and Gilligs are like any other mechanical beast out there. They all have parts and pieces that are attached in an odd or different fashion. But once you learn the why then you can understand the WTH stuff. And most of the WTH stuff was done because it made things easier or made things work better.
IMHO the Crown and Gillig are still the crown jewels as far as buses are concerned. If you have an opportunity to purchase one that isn't all beat up it will be well worth it to you to do so.
Good luck and happy trails.
