So, I literally just traded in my 2013 F150 for a 2020 Tundra; prior to the 2013 F150, I owned a 2004 F150. Here's my take.
I actually had no 'real' issues, in a sense, with either of my F150s. Both of them ran for miles (230K and still running on the 2004; 124K or so on my 2013). I didn't really 'need' a new truck. Why did I get rid of mine, and not go with another Ford, then? I'll list a few reasons.
1. I tow on a semi-regular basis - not enough to *need* a super powerful truck, but enough so that I need something powerful enough to handle it. My 2013 F150 had the 5.0L, and while it had plenty of power....it did NOT make it down low. Towing a 24' camper, I often had to go to 3rd (or 2nd!) to be able to maintain anything like a decent speed. Running at 5000+ rpm in 2nd gear at 55mph for hours is not the brightest idea, in my opinion.
2. It had plenty of tech....but said tech often failed me. I had the Sync system, and while I can't speak for the newest stuff, I can tell you that the Sync system in my truck was THE biggest piece of crap I have ever seen in my life. ...but after 6.5 years of stuff constantly just....malfunctioning for no reason, then 'fixing' itself, and the cycle endlessly repeating...it drove me nuts.
3. MPG ratings were not accurate. Granted, I live in the Ozarks, but I'm not exactly driving up a 90 degree hill all of the time. With about 75% highway and 25% city driving, I got a whopping 15.9MPG - and that's driving it like Grandmas was in the passenger seat with an open cup of coffee.
4. For me, the single biggest reason I got rid of it was because when it comes down to it, I don't care if it has the newest tech or not. I DO care if the tech that it has works well. For example, seat heaters, multimedia, etc, are nice, but if they don't work, I don't care.
Like I said, the truck never failed me; and even though I LOVE my new truck, I do have to say I miss the old one somewhat. It saw me through some hard times (wife's hospitalization, the loss of my father, etc.), and for that it'll have a place in my mind...but when the recent downturn hit, and given that I was looking for something with a bit more power, I decided to visit the nearest Toyota dealership.
As such, I ended up with this last Friday. So far MPG is right at 14.5MPG, and that's driving it like I stole it. I have no doubt it'd get 16-17MPG on the interstate; and the torque down low is fantastic, as is the build quality.
