Both vehicles have been meticulously maintained and driven mostly highway with an offroad trip here and there. Are the mileage totals worrisome on these two vehicles? What's the useable life of an F-550/6.0L that's been taken care of properly? Would the '07 be a safer bet given the 6.0L's history. Thanks for any help.
Don't let the good maintenance fool you. Took care of mine religiously and it ended up springing oil leaks everywhere at 85-96k miles. U gotta check those deltas, oasis and most importantly look underneath with a flash light around the rear oil pan and towards the heads. Good luck!
