Keep clean oil in it, keep the chassis lubed.. DRIVE IT.. (busses like to go and not sit for long periods of time).. DONT get it's engine hot, DO keep the tire pressures at spec.. and your bus can last you a very long time and as lot of miles..

School busses are medium duty trucks.. in fact if you noticed the conventional (has a hood like a truck).. are the same chassis that Straight Box trucks are made of.. many of these box trucks run 10-14 hours per day every day.. school busses run a couple hours a day.. so a well taken care of bus is just barely broken in when we buy them.. so they have lots of life and adventure just waiting for you!

Like cadillackid said, the T444E is a little weaker in a full size, but I have a 40' with it and I last had a 30' class A motorhome with a 454 cabed engine and the diesel bus still would kill that gasser going up hill with more than double the 30' weight. and then there is fuel, doesn't cost half as much to run the bus...
Man that was fun busting that RV up, it left me started many times on the interstate.
I hate having the engine in a doghouse setup it makes the rig too loud to talk and makes more heat, I love a rear engine unit, so much better!
Stay away from CAT engines, they are more costly than they are ever worth. Cummins 5.9 are too underpowered for these I wouldn't recommend one, the 8.3 is a much better engine.
I'd love to have a DT530 in a bus but I don't know if they ever did...

They did. Iíve seen them in big RE buses with the 3060 transmission.

They come up for sale in Arizona all the time.
I want a DT530 in a short bus, but that would be a custom build for sure.

JD's coach will likely outrun the lot of us on a big hill. Even at 43k #. A little different animal than your typical school bus.

The Crowns with 671 Detroit or Cummins 855 would be great contenders.

As far as common school buses go, I would be looking for a big motor and 5/6 speed transmission.

The DT-466 & 530 or Cummins 8.3 backed by an Allison 2000 or MD-3060 would be good drive train choices for Mountain driving.

I used my Bluebird RE with the 8.3 and MD-3060 as a moving truck over three mountain passes in 95F+ temps and was able to pass the semi's and RV's that were in the right lane with flashers on. I could not keep up with the car traffic.

If topping the passes at 60+ is important to you a later model MCI or Prevost may be worth considering.

It costs $$$ to go fast.



When you consider the vast majority of school buses spend 95%+ of their service life at speeds under 35 MPH there isn't much call for buses with big HP and high speed rear ends. As a consequence most school buses have power and gearing to pickup/dropoff kids going to/from school.



There are the unicorn buses out there though but because they are so rare they command higher prices. Most of the big HP buses with high speed gearing are set up as trip buses. They will be found in places like WY and MT where a short extra curricular trip is 200 miles one way. 300+ HP and gearing to go 80 MPH is not unknown in some of the trip buses out west.


Our church has a Gillig Schoolcoach for sale. It will cruise all day long at 60 MPH, even while pulling an equipment trailer. It will slow down on the hills because the DT466 in it is rated at only about 210 HP. There are easy ways to increase the power but you will then run into the problems every rear engine bus builder has run into and that is keeping the engine from overheating. The way it is set up currently it does not overheat on a long uphill grade with a full load on a hot day.


It also has pass through under the floor luggage compartments with two luggage doors on the street side and one on the curb side.


The 78" ceiling height is a real plus as well.

Mine does better then I would have thought in the mountains, keeps up with the trucks.

However the short bus I have to work on, we got a 6-71 Detroit for it, 250 HP. Mountains what mountains?
