Peterbilt mx or cummins?

NO & Hell No

 

I would take a Cummins X15 every time and I have driven both. There is nothing impressive about the MX13 other than how quiet it is, it is just adequate at best in terms of power output. Cummins is better hands down terms of power output and ease of accessing service and parts. If you intend on keeping the engine long-term I would have far more confidence in an overhauled Cummins as well.

 

80% loaded as a bull hauler I somehow doubt that lol

 

Depends on where you live and what you’re doing and who you’re hauling for. Even back when I was running California all the time the run we had set up would be 20-25% deadhead is all. The deadhead leg of the triangle from CO to MT was 850 miles or so, the deadhead in CA was minimal because the fats out of MT were going to Fresno.

 

Ah I guess the ones I see around TX KS OK NE say they are almost always deadheading like 400-700 miles lol

 

It can be tough to put stuff together without the right connections. My brother lives in NW Kansas and the guy he pulls for has 5 trailers and a couple smaller feedlots so they do haul mostly the stuff he’s buying for himself or that other people have bought to feed in his yards. If they have to go down into OK or TX and load calves back they can usually take fats down to Liberal or Dodge City to get part ways there.

 

Everyone will tell you to stay away from the Paccar because it’s only a 13 liter engine. But based on the 545,000 I’ve put on Paccars in my last two trucks I personally would have no issues hooking on to a cow trailer with one. But I also spent about 4 years in my FLD running a couple rounds a week out of CA with a 12.7 Detroit and 10 speed and people said I couldn’t haul cattle with that truck either. So I may not be the best person to ask for their opinion.

 

I mean....your not wrong. I pull an end dump never under 80k all over the country over mountains, flat ground and everything inbetween.

However, my and many others experince with paccars from a maintaince PoV was the paccar was an absolute nightmare level disaster. Id tell you to get a maxxforce before a paccar. Smartest move would be to get a pre emissions rig of either cat. Detroit or cummins. But if you must choose an emissions rig then the cummins would be the best bet. Detroit wouldnt be bad either. Mack with a MP8 would also be a good choice.

Just dont touch the paccars. They are natorious for either being good if maintained perfectly from day 1 and your lucky or absolute wallet busters. But im also baised as hell.

 

You’ve had a bad experience getting one second hand. I had a good experience with a second hand one and so far a good experience with a new one. Our experiences shape our opinions, and I’d never tell someone not to do something because one guy on the Internet had something happen to them.

My friend runs a mix of Paccar and Cummins, and so far he’s overhauled one Paccar at just under 470k miles but he’s had to do 4 X15’s for various reasons. I’m not sure the mileages on the Cummins but I know one was around 220k. The Paccar was under warranty and they sent out a new long block and that truck was back on the road within 2 weeks.
