My 03 silverado would shift really rough on Tow Haul mode. Buddy with the same truck noticed the same thing. Shifted hard enough to make you think it was better to leave it off for that particular truck.
Currently have an 02 7.3 and all it has is a button to ditch 4th gear. Not sure if it adjusts shifting and torque converter slippage.

I think engaging tow/haul will also keep a good charge going to the trailer battery.
I will have to think about that one!
I think he means higher rpms (theoretically) in tow haul equates to higher alternator output. (like my old Chevy).
But as you also know, the charging systems are quite regulated on newer vehicles and long trips, the rpms won’t be any different on the open road tow haul or not.

Actually, what I have read is that with Tow/Haul engaged the alternator is programmed to keep providing a significant output rather than dropping down so much after it replaces the starting draw. This may not be true with all brands or years. I haven't verified if this is the case with my Ford, it's just something I read that I thought was interesting and a welcome feature. I have a little meter I can plug in to the 12V receptacle, maybe I'll investigate the next time I drive the truck.

I run TH and EB most of the time, although I don't generally run EB this time of year because I don't want to be in the habit of putting it on when it's below freezing every night. EB and ice isn't a good combo.

I activate tow/haul when accelerating and decelerating, but I find I can deactivate it at speed on level ground with no headwind. If the trans shifts out of OD I know it's time to activate it again.

I engage tow/haul as soon as I hook up the 5er no matter the distance, speed, or terrain. And I use tow/haul descending some steep winding grades even without the trailer behind. Less need to use the brakes.
