I happen to have a 2019 F-150. Mine is one of the most common configurations that you’ll come across ( Supercrew, shortbed, 4WD, 3.5L Ecoboost, A10). Bought it new, it’s been flawless, though it is a second car and I only put around 5k miles year on it, if that. I have the XLT 302A, so you get things like navigation, power windows/locks/pedals/seats, heated cloth seats, a rear e-locker. You don’t get leather and you don’t get the proximity key with the XLT unfortunately.
I did an overview of the truck when I got it. You can skip the first few paragraphs of exposition
Lifetime fuel economy has been 19.9 MPG, with thrift reaching as high as 24-25 MPG on the highway. I’ve always been impressed with the 3.5L Ecoboost’s low and mid-range grunt, it’s a great truck engine IMHO. The 5.0L is fine as well, but it’s a higher strung engine.
My previous truck was a 2014 F-150 in basically the same configuration (first gen Ecoboost and the six speed being the main differences) and exterior/interior colors. My brother now owns it and he has racked up the miles on it. I want to say he’s around the 220k mile mark now. He did have one of the turbos fail around the 180k-ish mile mark, but he decided to have both turbos replaced and have the timing chain/chain guides, and vacuum pump replaced at the same time as preventative measures. But other than that it’s been trouble free.
