[laynepaving]

the short version; currently running mx13 epa10 @ 380 hp w/10spd.single drive axle 9yd box(dump) 35k#gvwr.2012 pete 384.the mx 13 part of this equation has been a real money pit.last 3 years have been 3k,1500,and 3k =7500.00 in repair bills.i'm tired of having to pay to work.would like a truck similar to what i have but don't know if there is a more reliable version of the mx13,what year?is anyone familiar with the pc-7 or pc-9.and.......what is the reliability of the detroit motors.imo the mx13 is a super motor but the aftertreatment issues along with the lack of knowledgable mechanics @ 125.00 hr and paccar wants about 6,000 for all the crap you have to buy into to work on it.anyway, any thoughts.........thanks in advance.

EPA2013 is an improvement, and following all the maintenance guidelines helps too, and of course minimal idle is going to be a big thing.
