Exactly. I used to own a '13 F150, and had multiple issues with it *AND* the dealership. I was able to tow a 22' camper with it (notice I said I was *able* lol), but it sure didn't like doing so.
When I purchased my Tundra, I literally wanted a truck that could tow the same thing, but more reliably and easily, and the Tundra fit the bill. The funny thing is that while I'll never say the Tundra gets great gas mileage...it actually did BETTER than my F150 (5.0L). Additionally, it has the 38 gallon tank, so I can tow for about 350 miles at a time, even with a large trailer/camper. That is invaluable.
But more to your point...I routinely towed for hundreds of miles in areas where there wasn't any sort of charger within 100 miles (literally). When you've been broken down in the middle of nowhere in the middle of winter almost literally praying for someone to come along...reliability is a BIG deal, and adding another component heavily affecting towing ability to that isn't the way to go when you tow in areas nowhere near chargers.
Now...would I buy a hybrid? All day long....but my '20 Tundra is paid off.
