If the transmission programming allows for the shift to whatever gear given the load and maintain it, there is NO lugging of the engine. If it won’t maintain, it’ll drop to the next lower gear and remain there because the transmission is programmed that way. Whether my engine is at 2600+ in 6th or 2200 in 7th pulling 7k# flat towing, the engine temp is exactly the same. I know this because I’ve towed 1000’s of miles this way and monitor my gauges. What you don’t want, is to have the transmission hunting the higher gear, constantly shifting back and forth. This will increase trans temps which should be avoided. I set trans to 7th gear with 3.92s. It’ll tow in that gear and maintain.That's incorrect. The lower the RPMs while towing, the more it lugs, the more it builds heat. That is a fact.

I Tow a 30 ft 6,000# Travel trailer I put the tow / haul mode on . The downside is the mpgs . I get about 8.5 which sucks. I’m thinking of turning off the tow mode to see if I can get a mix of at least 10 between the 2 modes”
Then authorities like YOU come out and post “You’LL BURN IT UP if you don’t use TH”…. LMFAO … NEVER tried it but know EVERYTHING about it.
I towed 3x in 2022 across (4.5% grade) and back (5.5%) WV , VA not using TH through the Appellations. In Nov 2021 I crossed going South using TH as this truck had under 1500 miles and was first time towing for me. When I returned North I didn’t use TH. I post as someone that has Actually done it using both methods.
I don’t care if you use TH or not, same as I don’t care that you use 10w40 in your Hemi because you think the factory recommends the wrong fluid weight. But my advice to the OP of this question is based on Actual use (1000’s of miles) of towing without using TH. Trying towing without using TH won’t hurt anything !!!!
