Yep... Get your context. And agree for the most part. If F150, seems like the 3.5 is a durable powerful option. It is good to have choices. From what folks hear, it is good for 350-400k miles before scrap time.
But then, Nissan now will have the Cummins V8 turbo diesel in the new revamped pickup. Should do better under massive load than gas V6 turbo. And good mileage under light load. I have not heard about how the Italian diesel in the 1500 Ram does in situations like yours.
I am at a Hyundai dealer as we speak. Just drove a 5.0 ultimate. Waiting on them to find a Monticello blue. With its extra weight, a TT 5.0 would be nice.

much slower off line than my current first gen. It is a great car, though. Cannot imagine a Ultimate Genny with a 3.3 turbo that may sound less manly than the already less than manly SHO 3.5TT.

And I will not buy a car with some goofy sound injection system into the interior to fake out the mind, changing wheezing sputtering non V8 sounds into fake V8 like sounds.
