2012 Platinum - 75 ft from door
2015 Lariat - 10 ft from door
2019 Raptor - 75 ft from door
I kept telling myself to take the 2015 in to get that fixed, but was waiting for something else to pop up for warranty work, but never happened. I had to do the whole flip the visor down, open a door shenanigans like you mentioned as well. I vaguely remember seeing something a long time ago on the F150 forum about crappy homelink range, but it's been too long, and had too many beers since for me to remember what was said.
If you haven't already, maybe try resetting the homelink frequencies on the garage opener, re-program the handheld remote, then re-program the truck remote. Not sure if that will help, but if you are looking for things to try, might be worth a shot.
