I dont drive mine that fast either... its just spoeeds ive come up with (assuming gearing) that certain drivetrains are capable of as a ball-park to start at..
we all see the posts "bought a bus and it slows down on the hills.. or doesnt go fast enough" etc..
then we learn they have a T-444E / AT545 in a 12 row conventional going up the rockies...
put a T-444E / AT545 in a 6 row short-bus and drive it mainly on the flats with mild hills like apps, smokies, etc and its a fantastic and usually affordable combo to find...
pasrt of the issue here seems to be the one-size-fits-all mentality when it comes to drivetrains.. when it really matters a ton what you are going to do with your bus and the type of bus you are going for.. no reason to send people on a goose chase for a big engine and an MD-3060 if all they want to do is taske their bus 10 miles each way to the lake and back every weekend.. or its a tiny home parked for months at a time..
on the same token we want to guide people into staying away from a 5.9 / AT545 when they plan to run their bus cross country all the time and want to do it at 65 MPH... in a full size bus...
I think of my own busses as examples.. my DT-360 / AT545 works great staying east of the rockies and running 55-60 on the highway.. running it at 65 and it works hard / runs against its rev limiter all the time and gets much worse MPG... its great for me because i dont need to get anywhere fast when im taking the skoolie out..
the new shorties T-444E / AT545 is geared taller and is a MUCH lighter short bus... its speed limited to 62 but that bus i can see easily running 65..
but like i mentioned earlier put that drivetrain in a 12 row and its gonna choke.. big time...
cowlitz guide is an excellent place to start for bus types and what each means and some of the pros and cond of each..
it would be kind of cool to have a "builder" of sorts that would suggest types of busses and drivetrains based on quiestions a user would answer about their intended use and size of bus...
