Got 271K+ on mine, with no issues. Transfer case can have a pump rub problem but Merchant Auto has a fix for that. You will need to get good, as clean as possible fuel to your injectors so a lift pump and/or Nicktane adapter plus additive in every tank will help them. It the price is right, go for.
