Long haul 
2005 Nissan Titan Crew Cab 4dr Crew Cab XE Rwd SB (5.6L 8cyl 5A)
Long haul experience
 It's been 2 1/2 years since I brought the Titan home with only 5 miles on the odometer. Since then more than 65,000 miles were put on the truck and the engine power just getting sweeter. The original Bridgestone Dueler tires seem to have about 20,000 more miles on their treads. I got about 18 to 19- plus MPG (2/3 of the driving was highway) with a few times of 21 MPG. Everything on the Titan remains stock with no modification, except a recently added toneau cover. The driver seat is losing its support on long trip now.
