@DayWalker 'preciate it. Feel free to add me to any truck topics you want
I would avoid the new F-250/F-350 with the pushrod 7.3L engine as it’s too new and we don’t know how long it will hold up. Why be a guinea pig for Ford? (They are not even paying you to beta test for them :-)) Also, the 10-speed automatic transmission it is mated to already has issues in the other Ford trucks and subject to class-action lawsuit. To be honest, the jury is still out on the longevity of the 10-speeds from any manufacturer so I would personally avoid them if you intend to keep the vehicle for as long as possible (which you stated it is).
For the F-250 gas version, I would consider the true and tried 6.2L V8 with the 6-speed AT.
That is a lot of weight to tow for the poor Tundra - that’s my concern even though it is rated for that but you still don’t want to max it out. What about an older generation Silverado 2500 or GMC 2500 that Scotty reviewed below: They were built much better than the 1500’s, but I would trust the older 2500s better over the newer ones.

I would go F250 personally, the Japanese have shown no interest in building up their full size truck line. Ford super duty trucks , in my opinion, are still decent. The 10 speed transmission is still a little finicky but the 6.2, 7.3 gas and the 6.7 diesel should be great motors.
Definitely don't try to put an old tundra through that. You will most likely blow it up.
I know you said you don't like diesels, but the 6.7 powerstroke has been a great engine for fuel economy, power, and reliability.
A few stories about death wobble have gone viral. But remember how many trucks Ford sells every year, and compare it to the number of death wobble complaints...
The 6.2 is a great powerplant. It has proven itself rock solid over the last decade.
The 7.3 is untested. While it may potentially have problems, it also has been getting great reviews from enthusiasts and contractors alike for its smooth power.
Honestly I would pick up either the 6.2 or 6.7 in either an XL or an XLT 250. Unless you have to have a bunch of interior toys, the lower trims are great value.
But if it was my choice, I would go 6.7 powerstroke XLT 4x2 and never look back.
