I too Have owned Datsuns and Nissans for many years when I lived in Pittsburgh PA.
Since moving to SC 22 years ago have owned 5 Nissan's,2 different dealers support here sucks to say the least.
I had a Titan before my Frontier, I got about same mileage from Titan as my Frontier using my trucks as hwy warriors for my business.
My Titan had only one problem and thank god I am not dead. My rear end went out of my Titan because I had rear factory locker since I had off road package. It broke down in West Virginia not more than 5 miles from a great Nissan dealer. They took great care of me and Nissan USA stood behind that problem.
I Decided I did not need a full size truck any more and got a midsize frontier,because it drives more like a car than a truck and was comfortable even driving 16 hrs non stop on business trip.
I was disappointed my Frontier did only slightly better mpg than the Titan,also Frontier has crappy turning radius as did my wife's 08 Max.
If I would have better dealer support I might have considered a Titan.
My real choice for my new truck would have been midsize truck with Diesel, but no one here in USA builds one.
I do not like the government shoving ethanol down our throats they know you do not get the same mpg from ethanol gas as straight gas.
They also know ETHANOL ruins a motor but they are going to up the ETHANOL PERCENTAGE from so called 10% to 15-20% so I have read fuel economy will suffer more.
The USA has to make the move to clean Diesel as most of Europe has already done,it makes sense to only have one fuel.
There is currently your 3-4 grades of hwy gas depending where you live,plus winter blend,California blend,northern winter blend to prevent fuel line freeze up,and racing gas.
If EPA and government stopped all the blends and made only one mid grade the price of gas would drop by $2.00 or more overnight.
I have made the choice for me is DIESEL.
PICS OF NEW RAM HERE.
