Okay i am a ford guy but saw a 3500 pulling out a big buggy and truck all at once anf had to have one. I ordered a new one so i can have it my way. I pick it up tommorow. I have heard of some good fuel mileage reports was wondering what i should look forward to. I know the filter fluid is a little expensive and i will be useing alot of it. I want to do exahaust first but it seems the banks runs the coolest anybody use anything on the new 11 trucks yet. It will be used for towing and daily driveing. A dully crew cab long bed 4x4.
