Ok thanks

 

The best Dealer network is Cummins , but we have some good WS dealers in Saskatchewan too.

 

The warranty on the Isx is just done this month.
I have a diagnostic tools with Cummins insite and I put on the truck and nothing wrong. I work before with Cummins engines and I am comfortable to fix them.
But I Don t know If I want to go with detroit, my only problem with detroit is I don't have a dealership near to my home.
Thanks for your help .

 

Ok , thanks I think I will go with the t680 with Cummins.
