DDM,
Just my opinion here. If you're thinking of going from a Tundra to an 6.2 Ford in order to gain power, don't do it. You may gain some but not enough to be of consequence. Go diesel for power.
If you're thing of going from a Tundra to an F250 for additional stability with heavy loads and heavy towing, just go with the 6.2. The Ford gasser might even do a smidge better on fuel mileage than the Tundra.
I drove diesels (Cummins) from 1998-2019 and love 'em. In 2019 I downsized my hay trailer from a 27' gooseneck to a 20 foot bumper pull. I also went from towing 4 horses to 3. At the same time I sold my diesel and found a 2016 F250 crew cab with a 6.2 gasser. I like my Ford alot but I miss the diesels when I'm going uphill with a load.
