After only a week with the truck, I can't offer any long term evaluations, but I can say without reservation that it is easily the finest truck I've ever driven. I love this truck. It's the perfect size, the V-6 engine has all the power I could ever want, and it's a sweet looking ride. The seats are comfortable, the ride gentle, but firm. It's as quiet as most sedans and well manored. The price is reasonable too. The fully loaded Frontier has everything I would ever want in a car or truck.
The only this I could add to this truck is a battery conversion like the new Accord has. Upping the gas milage 10mpg would make it unnecessary to own anything else. This would be the ultimate vehical at that point.
