After looking at all the pages of this thread, I think I found a blue unicorn with the truck that I'll be getting soon - SuperCab, Lariat, black package, FX4, and tow package. I haven't even seen it yet because it's at a different dealer, but I'm hoping to get it sometime next week.
Just passed 1,000 miles so hooked up the boat and drove it to shop for annual service. Boat/trailer weighs just under 4500 lbs. Can definitely "feel" it back there more than when I had the F-150 doing the pulling. But that 2.3 pulls like crazy... no problems at all.
