The Frontier Truck 2014 has the worst ride I've ever had in a light utility truck. Sold my Mazda 1999 that I had for 16 years and wish I had never parted with it. The seats in the Frontier are so ergonomically inferior that when driving, you feel as though you are in a roller coaster. You body turns from side to side as the suspension in the truck does not absorb any bouncing or bumps. The seats are very uncomfortable that my wife and I are now in constant pain as I write. Never had back problems before. I regret ever purchasing this truck. I even tried the SV model, didn't learn the first time. It's the same design but better seats, some what better but the damage is done. Back pain. Stay with the proven trucks that offer a smooth ride and good gas mileage. Nissan is trying to make a truck but had the wrong concept. The mileage is very good on the six, the engine is good however, the cabin sucks, uncomfortable, seat adjustment there is none and the head rests point the opposite way.
