I hear you on the dealer issues. Not that is anywhere nearly as far to drive, but I drive my truck 20 miles to the dealer I purchased my '18 from new to have them do anything more than an oil change. The in-town dealer that is about 3 miles from my house is full of a bunch of tools, and when I was going to buy a Superduty diesel from them and was asking about having a front locker installed before I picked it up from the order I had to explain their 'lead drivetrain tech' what an electronic locking differential is and how they need to install it---once that started, I have never gone back for anything but the basic oil change, and yeah, I take them Amsoil to use for even the oil change.
The dealer I go to for Service, Wright Ford in Redmond, Oregon, set up an appointment to diagnose the phasers this last March, called when it was diagnosed that afternoon and let me know if would be a while until the parts would be in and no worries for me to drive it in the meantime...they called last week set up for a 2-day service appointment to have them changed out for May 9-10th, 2022.
Good luck, not sure where you live, but if you are anywhere in the NW I would recommend Wright, and even help you out getting it in, picked up,etc.
