After my 2018 Gen2 was totaled Rather than waiting for the Covid era Gen3’s to start hitting the lots I opted to find a 2020 w/o sunroof b/c I KNEW I’d be getting the most “sorted out” version of a gen2 possible, a late build 2020 w/ no pano roof, no cam phaser issues, & all the lil details they tweaked along the way during that 2015-2020 F150 run. I’m very happy w/ the decision & have nearly 50k trouble free miles thus far on it.
So yeah- my vote would be try to find a 2020 ideally, or a 2019, I wouldn’t mess w/ a 2017-2018 & play Russian roulette w/ plastic pans & cam phasers
