Feel Lucky
I attempted to drive one of those when I was a co driver and they were servicing my assigned truck.I was only in it for one delivery .Head mechanic told me to just use the high side[drive it like a 5spd,peg the tach and shift,repeat,repeat,repeat lol] on the highway and low only on the jobsite.
I managed to make the run,but couldn't wait to get back to the yard with it.
I didn't want to learn how to drive something I would probably never be in again,as we had other trucks we usually used when our primaries were being worked on and this was mostly a yard dog.
Yup I use high on road and low off it takes off in high first like most do in low second.
Fifth does some wild crap kinda intermediate it seems you can remain in it on the road down to 45 no problem. It tops out at 70 mph but that is as fast as I care to go anyway and am usually at 50 to 60.
