NE ND | FWIW, I have two M11s at 370. Plenty of power, but not boatloads. Been decent for reliability. Brother has an L10, not too bad. Parts man at local IH truck who has been there forever states L10s are as tough as nails.
I had a 7 spd spicer in a truck. I got used to it but new help IMO really struggled. Pulled it out and put in 9 spd and everyone is very happy. I have 9s and 10s. If I was a professional trucker I'd want a 13 or 18, more gear selection. | |
