Leesburg, Ohio | I like the Macks. Had two R models with 350's that were trouble free. Last one was an '03 CH613 with a 427 E7. Seemed to always use just a little coolant, but never could figure out where it went. Not enough to be an issue. Someone told us it could have been in the EGR valve, but never checked it out. More than adequate power. Only thing I did not like was the 10 speed it had. | |
