Pete 579 vs Volvo 780

First off, you're going to be downsizing from a 77" Condo Sleeper into a 66" Mid Roof Sleeper with a lot less storage and interior space then the Volvo.

If you can live with that, than you have the choice between the problematic PACCAR MX13 engine vs. the Cummins ISX15, which has its share of problems also.

For the least troublesome combo, I would stay with a Volvo 780, D13 with a 13 speed manual. The I-Shift may be nice, but it's another electronically controlled part of the truck that can act up at any time.

 

cm2350 isx engine is not bad. we have a Volvo with that engine and only one nox sensor is replaced, the engine has 320k miles. however d13 is more fuel efficient

 

Yes that true, any ISX15 2014 or newer is a good choice.

At the present time the CM2350 and the D13 are both good choices.

The ISX being more of the powerhouse vs the D13 good power and fuel economy.

 

My Pete 579 has 105,000 on it. Has the isx15 in it. It's a company truck, but I treat it like it's mine. The truck has been great. No problems. The motor is rated at 425hp. It pulls good, and no problems yet.

 

what year is your truck ?

 

2015. I've had it almost a year.

 

yeah you have that cm2350 isx engine.

 

I got a new fedex freight volvo thats was manufactured nov 2015. It has cummins isx15 but not sure if it is cm2350. But the bad thing is that who ever was in charge of fleet lowered the torque instead 1550 ft lb, it is 1450 ft lb. Pulling at 13k pounds, always drops to 8th gear on I-80 in PA.
