I have an MBE-4000 in my freightliner SportChassis M2-112, and love the power aspect very stable truck. the only problem I have really had was the EGR valve can get stuck if you don't drive it very much. I have found that I need to drive it every month under load to keep the valve from getting stuck. between truck and trailer I am running right at 43,000 pounds . this truck and motor makes it feel like there is nothing there.
