If I were looking at a diesel, I would have to look really hard at the Cummins. I have scads of v diesels, and I like them. But aside from the Duramax and the old 7.3 Powerstroke, the Cummins is tops.
One thing to remember is that these pickups have quite tall tires, so final drive ratio is good. You should be okay to cruise with the 4 88's, but then again, you should have good power with the 4 11's.
The newer F550's I have driven were all regular cabs, and turned really well.
It would be good to know the difference between the two brands though.
Geeze, its fun thinking about spending someone else's money!
