DD16 Reliability

What year is it? Auto or stick shift? That all can make a difference?

 

probably not.

I have had 3 DD16 in a row - a 2014, 2018 and 2021.

I have had very few issues with any of them - emissions or engine.

I run heavy all the time (50% anyway) with empty weight near 80k.

I trade trucks every 3-4 years - so men are always under warranty and go on to the next owner with about 300k miles.

Fuel mileage does not factor into my equation- so I am ok at 3 mpg loaded or 4 mpg if I am not that heavy. Or maybe 5 mpg if I am empty.

I know of at least 2 others that do the same and have also had very few issues.

not sure this helps or applies but there it is.

 

Well, I could order and buy any truck

I have ordered and bought 3 Western Stars with Detroits in a row. It is all about the spec and not about the logo as far as I am concerned. I have. No desire for a narrow cab or the $30-50k premium for a paccar product.

I know absolutely nothing about the Mack product.

I had a guy leased to me that ran Coronado with a DD16 with 18918b on 46k airliner with 46k rears and a 14600 steer axle. He was light enough that the steer axle weight was not a huge issue.

he regularly ran 130k and was able to do it with out a flip neck on the trailer.

I do not buy used trucks, so I can’t really help you there. Remember, all heavy haul miles are hard miles - my take is you won’t save a ton of money by going with such high mileage trucks. That is just my opinion- if you need to rebuild it is going to be spendy.

 

I ran a 2016 Cascadia Eaton Ultrashift MXP 18 spd, DD16 600/1850 from May 2016 to November 2021. Put 530,000 miles on it pulling 140,000 lbs.
4.5 mpg lifetime average. Engine itself was reliable.
Warranty stuff:
Injector cups after 2 years, diesel showed up in coolant.
Oil leaks around oil pan, oil filter housing.
Water pump at four years.
One-box issues after 4 years. They replaced it and installed new injectors in engine.
Auto shift Clutch went just three weeks before five year warranty ran out.
Non warranty: radiator cracked after fourth year.
