Sorry i meant to say they dont have an engine in any current Heavy range if truck. The isb engine is in the lighter ranges

I think your right, their only big truck market is in the US. ERF used to use the ISM but dropped it a few years back. Probably why they only really manufacture the ISB, ISC and ISL in any volume in the UK. Foden used to use cummins engines but they are no more..

You have to admit, the ISM and ISX do look like mighty fine engines, just no one wants them :P
