He wants towing power.
The higher the gears, the more leverage is on the engine trying to pull hills.
As long as he can do 63 miles a hour without over revving the engine, he is golden.
I'm not saying that the 4.44 or the 4.11 would be bad, just may not have the same power to pull the hills without dropping to first or second gear.
To the OP
I would get a rear engine bus for your needs. Better of everything.
Rear engine buses are Heavy duty truck chassis, VS front engine buses are Medium duty truck chassis.
I have to run for a bit. I will expand more on this in a bit.
