Eric,

Well, drivetrain wear MAY increase if you use full-time 4wd. However, this system has been out for a long time...and i know of NO report of any type of failure or premature wear & tear. The center diff being GEAR-based helps a lot in keeping maintenance to a bare minimum.

Tire wear will actually be more even if you use full-time setting...you may not even need to rotate according to some owners!

Fuel economy is the main reason to avoid getting full-time 4wd. But from EPA ratings, there is little difference between V6 and V8.

Hope this helps.
