OK, one more time:
I've had both the 4.7L and the 4.6L. THEY ARE TWO DIFFERENT ENGINES AND HAVE DIFFERENT TRANSMISSIONS. The 4.6/6 speed replaced the 4.7/5speed in 2009 (2010 model year) and was available until I believe the 2019 model year.
Towed with both, both will handle well over 3000lbs, but that much weight will wear out your truck brakes fast if you don't have trailer brakes.
IMO - the newer 4.6L with 6speed transmission is the better tow vehicle. The older 4.7/5 speed did have an overdrive lockout that helped, but it tended to "search" between gears more than I liked. The 6 speed has a Tow/Haul setting that actually changes shift points, holds it in lower gears longer before shifting to improve performance, and improves engine braking. Gotcha. 👍 I’ll just say this to the OP and let it go. My 4.7L/ 5 speed does fine with my boat, which is very comparable to your 3k lb trailer. From all I hear (including the official tow rating) the more recent Tundras are better tow rigs than the first-gen. So I think it’ll be fine. I do also think it’d be worth investing in a tranny cooler.
The CENTER will hold.

The 6 speed has a Tow/Haul setting that actually changes shift points, holds it in lower gears longer before shifting to improve performance, and improves engine braking. Small correction. The latest 4.6 models don’t have the tow/haul ass button. They just have the “S mode” where you can select the highest gear the transmission will use. So you can effectively lock out the 5th and 6th overdrive gears. It also turns off the “artificial intelligence-shift” control and the transmission operates like a traditional auto trans - which works fine for towing. Just keep it in S4 unless it downshifts to 3rd, in which case I bump down the gear selector to hold it in 3rd (so the transmission doesn’t try and shift back and forth between 3 and 4) until I crest the hill then pop it back into 4th.

Does nobody just slow down, run in 4th or 5th and keep the tach at about 2000-2250 for pulling with a gas motor?
Minimal if any shifting then.
Do the manual shift thing and keep the transmission in a gear that gets you to that 2k mark at highway speeds.
Of course I am speaking about a 5 or 6 speed here. No experience myself with the newer 8+ speed transmissions. Reminds me of an old thread. ""Can I tow a big 5th wheel RV with a 6 point something pickup?" And the responses claiming a diesel as absolutely necessary. Bull And Schidt That 6. something produces more snot than the original Super Duty. If you think Super Duty means a "big" pickup, Google it. Those engines were dragging 73,280# up and down our highways everyday for years. And we're among the Big Dawgs of their time. Yeah, I'm certain a 6. something can drag a measly 14Ä·# trailer.

What 6 something gas was used in what truck pulling over 70k? Not trying to start a pizzing match, just curious?

No 6. Something. It was someone's modern 6 liter the question was about.
Google.
And I was slightly wrong, but will stand by my comparison.
The Ford Super Duty 534. Was the engine I referred to.
266hp/490ftlbs.
Fords 6.2
385hp/430ft lb
Giving up 60ft lbs of torque is no big deal considering the pickup/trailer combo
weighs less than 1/3 of the old semi.
