I bought my 2018 new in Jan 2018. Drove it 1400 miles home, tuned it with MPT until Cobb finally released their AP & AT software. Switched to E50 right after that, so it’s been running tuned since new and just rolled over 85000 miles. I do my own maintenance & service work with 5w30 synthetic oil & FL500S filters. I just changed ALL the fluids in the truck. Transmission, Xfer case, front & rear diffs, coolant, and brake fluid, along with new brakes and a rotor cleanup, all done by myself at home. I have new rotors and braided steel lines on hand, but that’ll wait until “next time”.
Overall consideration, this truck is the most versatile, trouble-free vehicle I’ve ever owned. It has never seen a dealer since I drove it off the lot over 6 years ago. I’ve not done ANY of the recall/customer service crap because fugg the idiots at the dealer. I’ll deal directly with Ford or with Tasca Ford Parts online.
I’m about to install the bigger turbos, manifolds, downpipes, etc I’ve had few a few years now. It needs more power now. I was fine with it until I bought a new 21 Explorer ST with the 3.0 TT EB for my wife to carry the grandkids around back in April 21. It’s still stock hard parts as well, except intercooler and of course tuned for E50 along with some trick 10R60 tuning from ZFG. The problem is that it is so much quicker/faster than my truck. I mean the Explorer ST runs 11s @ 115 and the truck feels dog slow running 12.5 @ 108! Oh well… lol
