Buy the Tundra.
I had a 2015 Ecoboost a few years ago, bought it with 62k on it, got rid of it 7 months later with 68k on it. It was a really nice, clean, simple XLT model. No touch screen no extra bells and whistles except for a trailer brake. Crew Cab, short bed, nice pickup. I had towed a trailer ONE TIME with it, and never hot rodded it. In the 7 months I had it, it cost me just shy of 10 grand in repairs. Transmission, timing cover leaks, ignition coil failures, timing chain rattle (look that up on the ecoboosts, if that doesn't turn you off of one then I guess have at it). The one time I DID tow with it, I towed a small Honda Side by Side to an elk hunt, and the truck got 8 MPG down the freeway. You read that right, 8 MPG with roughly 2200 lbs behind it. When I got rid of it, my uncle told me something that's stuck with me: At the end of the day, turbo or not, it's still a 3.5l V6 that you're asking to do the job of a big block V8. The Honda Pilot has a 3.5L V6, and I doubt anybody would argue it's an adequate towing rig.
Dad bought a 2019 Ecoboost right before I dumped mine, bought it brand new. He just traded it in last week, it had 90k on it. He's a salesman in the HVAC industry and puts roughly 30k per year on his vehicles, but they're all unloaded highway miles. Typically he got 17 or 18 MPG on a good day when it was just him and he was running down the freeway, so nothing to write home about. At 35k, he lost the trans. Ford replaced it under warranty, but the new one never shifted right and would shift really hard alot of the time, especially when down shifting. It went to the shop multiple times and they could never figure out what was wrong with it. About a year ago it developed the timing chain rattle. Dad never could trust that truck, and he finally dumped it and he's glad he did. It's a shame, Ford builds a really nice truck, interior wise. But mechanically, they're horrible.
No experience with the 5.0 coyote, but in researching after I got rid of the ecoboost, you'll read frequently about cylinders wearing out of round at about 100k. It was common enough that there are videos on youtube out there from Ford mechanics warning people about that and to be vigilant and anal about maintenance.
Currently driving a half ton GMC that I picked up after I got rid of my Ecoboost. It's a good truck, I've enjoyed it, but it's a little under powered for what it is. I've got the 5.3, which GM has been using since the late 90's, so that gives some peace of mind. But nothing beats a Toyota for mechanical peace of mind.
