diesel generator

I ran a tri-pack for more than a million miles. - I can say with full confidence that it is an expense, flat out. Take this statement from a hyper-miler who is all about saving fuel. - From now on, I simply idle the truck when I want power to run things. It is cheaper than the long term care and constant servicing of that tri-pack unit, and the fuel differences do not make up for those costs.

The fuel savings of those tri-packs vs. a well tuned ISX engine with a 320-amp alternator and couple extra batteries idling at 800 rpm just don't add up over the long haul. This considering that the engine can be tweaked to idle at only about 12-15 mg/stroke via some custom programming. When engine is set this way, it competes with any apu and the cost is cheaper in the end to simply run the ISX.

That is my experience with it .. My apu now lives at a junk yard somewhere and I will not install another one. It was nice to have but in all reality, having the ISX idle set at a proper 800 rpm (because 600-rpm is too low for an ISX to idle at) and big alternator, is cheaper in the long run to operate.
