That's the point. Seen the price of a remanned or usable 6bt lately? I'm a college kid.
Well, since a DT466 won't work in a 1 ton, especially with a giant brick of a trans, I would say start saving for a B series. I just think a DT with a Road Ranger is just far too heavy. Now, if you could make a small Allison like the 1000 series or a Ford transmission work, then I'd say go for it. It's still border line of being too heavy IMHO.
DT466 is a good engine it's more of a heavyduty service engine than where as a 5.9 is more of a medium duty engine your not gonna be "bombing" it so theres no need for aftermarket parts . plus parts are cheap and just a available as they are for a 5.9 . and as diesel4me mentioned you can get a whole school bus for cheaper than running 5.9
Both engines are clearly medium duty. But, I would agree that on the very high end of medium duty, life would be a 'tad easier on the DT. With that, I don't think it's any stronger or longer lasting than a B series, it's just a little bit bigger.
Well put, and I'd really like to only buy one of these babies once or twice in my lifetime. I can stand being down a little bit on power from a bombed cummins for a stupid long service life. Besides, a factory trim HT570 puts out 700 ft lbs at 800 rpm and 1150 ft lbs peak...how much power does one need? What will a bombed cummins do reliably while moving 26,000 pounds at speed?
A factory Cummins would likely give you more life than you'd need. An HT570 wouldn't be even a candidate IMHO, it's heavier than a 466, right?
A mod Cummins should be fine around 350HP and 800ft lbs, with the correct turbo for that kind of power output. Basically, it would flat out-run a stock DT and still last 300K or so, maybe more if you were using synthetic and had the perfect turbo setup.
Regardless, I think a 1 ton is below you for what you want. 26K is not too bad for a 1 ton, and it can be too much for one....meaning if you drag around 26K every once and a while, piece of cake. If you are consistantly pulling 26K in a 1 ton than it's going to have significant wear on the chassis and drivetrain.
I'd be looking at a Ford F550. Get a lariat 550 with a regular dually box bed, 19.5" alcoas, leather, blah blah, makes some payments and daily drive that sucker!
