Yes, bought a 2021 F250 7.3 and tow a 30 ft 7600# trailer with full fresh water tank rendering a 1200# tounge.
The 7.3 paired with the 10spd transmission has exceeded expectation, especially in steep mountains where my previous 2500 struggled mightily.
In tow mode, the transmission utilizes all gears 1-8 and locks out 9 and 10.
Driver can also lockout gears on the fly making hilly country a breeze.
I chose 3.55 gears and occasionally see over 17 mpg on long highway trips and 10-11 towing in the hills, impressive.
Heavy towing, I'd opted for 4.30 gears.
I'm confident this 7.3 is going to prove to be a very durable engine with low maintenance costs as it's a simple design.
Time will tell but a very satisfied Superduty owner.
