Hello all. I have a 2011 6.7 stock. I'm planning on purchasing a truck camper and do some traveling. Before this I want to upgrade the suspension to air ride, shocks, better tires, tuner, air intake, sway bar, and maybe an exhaust. Not sure where to start or what all is justified. Goal is horse power, fuel mileage and stability. I'm not interested, at this time, in dpf delete due to the emission laws and so forth.
