First Truck .. Engine Help

[Mikiisx09]

I'm with you in this Rawze..I have 2 Trucks with CM 871,one has 1.2K miles( Volvo 2009) and 2011 Prostar with 600K miles. Just 2 weeks ago I bought 2018 Kenworh T 680 with X 15 Cummins for one of the Drivers.I did couple trips with new Truck but still nothing drives,pulls and handling like my RED BEAST with 1.2 million miles.All maintenance on Trucks I'm doing my self with help of my buddy Dr.Isx. Hi is member of Rawze.com as well.In my 12 years of trucking I tried couple of Detroit engines as well..they not bad at all but still Cummins is number 1on my list<CM 871>.
