Me thinks this is a classic case of 1st generation teething pains... the duramax/allison has been paired up for a decade now (not counting the short stint the ZF6 did on there).. they've had a long time to optimize the platform.
Even with the Ford lagging behind a little, it's nevertheless still a beast that can tow anything anywhere.... I came very close to getting it but shied away because the engine was just soooo new..
