I've had the Nissan Armada for 7500 miles now, drove it to Florida, and have made many trips to the lake with our toon. I gotta say, I'm impressed. The drive train is pretty slick. The 5.6 is robust and always responsive. It makes you want to punch it when pulling out on the highway..

. It growls a little with the stock exhaust and the shift points are firm and keep the rpm low. After Having two Expeditions for the past ten years and the shift program has the 5.4 screaming in every gear to at least 4500, which leaves you feeling like there's no low end, The Nissan shifts very low RPM making it feel like there's plenty of power in the pedal left.
I usually trailer in 3rd just to keep it out of the 4, 5 gears. They're too high for 45'in to the lake.
It'll run 75mph just under 2000rpm and it got 16.5 on our trip. Not the greatest in mpg's. Neither was the Expedition. Anyway, very good handling (air ride), and seems well built.
I've been a Chevy man all my life and love my 06 2500HD but the 6.0 in that truck won't hold a candle to the 5.6 in the Nissan when pulling the toon up the ramp and back to the house. I have to be more careful with the go pedal in the Nissan.
Oh I just remembered an example. The other day my wife pulled the boat up the ramp with the 2500HD and I stopped her twice and asked if the park brake was on. Which she sarcastically reminded me it wasn't ..both times

. It was laboring pretty hard though, I had to ask!
The Nissan on the other hand...has no problem and seems to move up the ramp with half the effort. Like something's back there, but no big deal.
It has a button on the dash to turn the beeper off in reverse
Still like my old Chevy.... It'll gitter done.
