Tow haul mode?

Pulling 10,000 lb fifth wheel with f350, 6.4 deisel.. do you have to always use tow haul mode even on flat interstates?

What does your owner's manual say?

Where is the EB button?

I have the same truck as you, 2011 F350SRW 6.7PSD.

There is no switch for the exhaust brake. It is always there. To activate, you just need to tap the brake.

I used it going down the Sunwapta Pass on Highway 93 in the National Park. It kept the whole rig at a nice even 80kmh. No stress, no white knuckles, no moving from gas to brake and back again.

If you are asking about Ford I don't know. On my Ram it is next to the TH button on the dash.

My F350 doesn't have an exhaust brake, just tow/haul. The magic is in the transmission-it does some pretty aggressive and impressive downshifting to bring the speed down,

I always us tow haul when the 5er is connected.

What I have read the Tow Haul is to lock up the torque convertor in the transmission. Without going to deep in it basically this reduces the fluid resistance that turns the internal parts that make you move. By eliminating this this will greatly reduce the heat in the transmission. This will reduce the problems associated with excessive heat problems and repair bills. With that being said I engage the button when I start the engine when I am towing. I tow with a 2006 Dodge 2500, 5.9 Cummins R 48 transmission with an added after market Aluminum transmission pan designed for cooling.

I would pay for an option that automatically turns on the tow haul mode when something is connected. My Chevy 3500 knows when something is connected anyway, so it couldn't be that huge of an engineering feat.

I miss having a physical switch that flips back and forth.

I always (try to) remember to use T/H, even on flat runs. If I forget (and have a couple of times) DW reminds me. LOL I've found in my Chevy D/A it helps to slow you down on the ramps as you exit the freeway. Downshifts a little earlier as you slow - saves on braking some.
