The issue isn't limited to the Ranger. It's happening right now with my 2016 Canyon 4X4 (that will be replaced by my new Ranger, if it ever gets here!).
I ordered my Lariat Super Crew 4X4 the third week of October. It's scheduled to be built the 23rd of this month. Who knows how long it will take to be shipped and delivered.
I have done updates on other Ford vehicles I've owned, and it usually doesn't take anywhere near an hour to complete. I do, however, agree with you. Ford needs to get into the 21st century on this.
