DD13,ISX12, MX13, Maxxforce 13

DD13 only decent engine out of those. Then there is also Volvo/Mack.

 

Maxforce is already ruled out as you stated, which is a smart decision in my opinion. As V8Lenny stated DD13 is a good engine I drove one and loved it but that was in a daycab. I do not know how it will work in a dump truck operation. Just my opinion

 

Detroit has got most things figured out. About the only choice out thre.

 

Been a while since I dealt with Cummins but I'd take them HANDS DOWN over the Detroit. Without a question.

 

The newer cummins is not what we were used to anymore.

 

The newer Detroit isn't what most think either. I oversee maintenance on quite a few of them (couple hundred) and I'd not buy one.

 

We have both , over 800 total.

 

Just relaying my experience. Couple hundred new Detroits, (about 300) total of 1200 power units (2005 thru units that came of the line yesterday). 50 Maxforce units. Those have been trouble free. Pre-lawsuit units.

I look over every maintenance invoice on each and every one of those trucks. Approve or argue most of them. Detroit hasn't "won" me as a fan in the least.

Prior experience was with CAT and Cummins at the dealership level. Much preferred working with the CAT folks. Maybe it was my local rep but he sure helped the average trucker a lot more than others would it seemed.
