Normal
Ford reman be their best /reliable option . I'm sure they get a break on the price and can eat the labor for their mechanic to install . Tell them to call you when it's done . Sounds like truck is in great shape . Anything mechanical can fail at anytime. Reman engine would come with a warranty. Have them change all the fluids . Buy your extended warranty that covers rentals . Sounds like a solid truck besides this incident. What did the Oasis report show for history on this truck?
