I am not brand specific. I happen to own a Ford f250 7.3. I have a diesel 3/4 ton on purpose, it's for my peace of mind and comfort. I would be just as happy with a cummins or a duramax. We shopped for 2 years before I bought my truck, it needed a little work but I really got it at a good price. The cliche "you don't know it's back there" is wrong. I still know its back there, but the power, stability, braking, and towing comfort is night and day between the f150, ram 1500, and Chevy 1500 I had before. We tow on the Blue Ridge Parkway and I can easily be faster on the ups than on the do
