Normally, I would agree but the 3.5 is showing some promise for a vehicle that occasionally has a near max load and loafs the rest of the time. If the vehicle spends most of the time working near the limits, I still feel there is no substitute for cubes. In theory, the 3.5 would be ideal for me but that little six is being stressed to unbelievable levels. Even though stress tests have been done on it that say it can handle the stress, I'm still waiting to see how it holds up in the real world. I'm also concerned with how much it will cost to get it fixed when it does break. Ford is a wee bit stingy with its warranties.
If I had to buy a new F150 right now, I would get the 6.2.
