I have an 05 with 80+ thousand miles on it and have never hada problem. I do the regular maint myself and have taken it back to Toyota for 2 of the major maint schedules. I beat the crap out of this truck, hauling rocks, wood, lumber, bricks, etc., etc. and have never had an issue. I also take it off road in 4X4 without blinking an eye and have never been stuck.
As someone else said, I drove them all and this was the one that got my buy.
Good luck.
