I have just recently purchased a 2000 f450 7.3 with 157k miles on it. I plan on driving this truck 2-3k miles a month on average. I’m looking for recommendations on what I should replace, upgrade, or specific things I should look out for. I just want to avoid unexpected repairs and costs as much as possible. Any advice would help a ton. I plan on installing a new high torque starter, but beyond that I really have no clue.
