I love the C15's for gravel hauling.
My new ISX at a 18% slope does not hold a candle to the old mans C15 on 55lbs of boost at 8,000ft with a 105,000 lb load.
Trouble free smooth as silk power and spool up time that is bar none the best. The ISX is ok motor just was not what I thought it would be.
I know the KW dealers realy have been pushing the ISX but if they had to drive them day in and day out on our roads I don't think they would be pushing it near as hard.
