If you go by numbers the Tundra wins, no question. If you go by real world experience then it's equal and I not talking racing either. My opinion, I don't like the Tundra's interior or most of the exterior. The ride is good but not better. I have friend, co-workers and vendors that have jumped on the Tundra band wagon. They like the truck and they also have their share of complaints. Suspension is too soft, sucky brakes, weird shifting trany, body flex (more on that) bad fuel use when towing, weak top end when towing, ect ect. First the body flexing. A co-worker got his truck catywhompas on the job site goofing around. He was purposely trying to climb a mound of dirt at an angle. he got up, got stuck and got out of the truck. Got back in the truck and the door would shut. Once the truck got level the door shut fine. I did the same thing and didn't have a problem. A vendor of mine has a fleet of Titans, 6 2005 4x4 KCs. The owner, Jose went and bought a new Tundra. He claims it gets worse gas mileage when towing and at HWY speeds it doesn't have the same power as the Titan, after owning it 2 months he can't give a good review just yet. You never hear a Toyota owner complain about mechanical problem, why? because they are too proud and need to justify over spending.
Me, I have two Titans with a combine 227,000 miles. Yes they have had issues. Both had the manifolds replace, both had rear seals replaced, both had front pinion seals and both had the upper PS hose replaced. My KC has been trouble free for 65K miles except for a rear seal that was never replaced. Dad's 2007 with 43,000 miles has never been to the dealer except for a bad battery. What is keeping me from buying another Titan is Nissan's current packages. I want the proper TOW package without all the other BS and I don't want the base XE truck with gears and no mirrors.
