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.

The 7.3 is available with 3.73 or 4.30 gears. I can’t see any reason for getting 4.30 gears. I think if I was towing less than 12 k lbs I’d want 3.73 gears and towing over 12k I’d probably want a diesel even though I’m sure the 7.3 would do.

If I'm not mistaken, believe the F250 7.3 only has the 3.55/4.30 gear options and also believe you'd have to move up to a F350 to have 3.73 as an option but only marginally sure.
