As for the power, 400hp and 413ftlb tq seems like plenty to me in my regular Titan. Just towed a 5x8 trailer loaded relatively heavy with the camper on and also loaded down with stuff over 1,000 miles from CO to OR. Truck had zero issue running in top gear cruising along at interstate speeds and this engine has a nice flat torque curve. Even managed 16mpg with e load all terrains, the camper, trailer, and lift. I find it pretty impressive given what I see unloaded midsized trucks get and it indicates to me a low stressed drivetrain.
