There was a member here who was closing in on 800k miles on his all original drivetrain '99 Limited 4Runner, the last time he posted. Like the people driving the million mile Tundras (which by the way were the old cast iron block 4.7 2UZ-FE, also found in the 4th gen 4Runner), he was in the oil industry.
The 5VZ-FE 3.4 has more in common with the 2UZ-FE 4.7, than either have in common with the 3UR-FE 5.7.
In fact the 1GR-FE 4.0 is similar in design to the 3UR-FE 5.7. Which makes sense since they both share more modern Toyota engine architecture.
When I was looking for a truck I was wishing Toyota had made the 1-ton Dually Tundra, which was headed for production until the last recession ended that. No 1/2 ton trucks have enough capability for what I was going to use one for.
OP, buy what you want.
