I am a transporter of RV trailers. Original truck was a '99 Ford. Engine blew @ 613k. Purchased Dodge only because of the Cummins engine. Mistake. Should have replaced the engine in the Ford. When you spend 8 to 10 hours a day behind the wheel you need comfort and predictability of functions. Remove speed sensor from the wipers. Cancel cruise when the brake pedal is touched. Turn off stop lights when driver removes foot from brake pedal (to release trailer brakes especially when on ice) Heater controls and flash to pass need more feel. I have had problems with the new emissions. Been to the dealer 13 times for a sensor on the DPF.
Cummins engine and the six speed automatic transmission.
Move exhaust brake switch to the shift lever, remove auto signal, remove all electronic delays. Remove parking lights from battery saver. Reduce axle maintenance. Make it more truck like. Add light on dash to indicate cruise is engaged. Place convex mirrors below the flat mirrors.
