I have a 2017 SuperCrew with 3.5 EB Gen 2 with 32K and it a beast!! If I am on a wet road, I have to use 4A or it will break the tires loose. The only issue is that I had to have the TSB done on the 10 Speed, but it all good now.

My experience has been pretty much inline with everyone on this thread. I've got 31K on my '18 and in a little over 12 mos no issues whatsoever. Been changing the oil every 10K with high end synthetic and matching oil filter. I do a bit of everything with it: haul a 3horse trailer loaded typically, 4x4 a bit and run up and down the freeway. I've yet to ask it to do anything it hasn't easily accomplished. Spoiled!

up to almost 35k and no issues. Auto stop/start 'battery monitor' throwing a code, but the motor is great. Stock so far (aside from upgraded intercooler)
