The new Ford 250/350's are exceptionally rough, my friend in High school had the same truck as you ahve now and I loved it. I think every truck has their strong and week points, I know I want a Ram more then anything, but until they catch up in the interior department, i'll be sticking with Ferds. When you do a lot of driving, the interior is the main thing you have to consider. Now if I were to make my next truck a diesel, I have no idea, Ferds are too rough, Dodge lacks my taste in interior, mega cab is too big, quad is too small, so maybe a Chevy
That hurt to say.
Its all personal preference and application I guess, If It was a city truck that I didnt' drive a lot, i'd go dodge diesel quad cab, nicest looking and great drivetrain.
