One more reason to use it is a bit more braking in a panic stop no matter where you are, that seems like a good idea. Don’t ask me how I know this.....

Need advice on when/where to use 'tow/haul'. Use only when ascending/descending hilly areas? Keep it off when on flat roadways? Exactly what does it do i.e. does it restrict the transmission from it's highest gear? Keep it on all the time when towing? Thanks!


Great info from all. Many thanks! Nothing like receiving a bit of free 'education'.

What happened this time? Usually have at least one person say that they never use it. For me, if I have a trailer on the back, have a load on the truck, or I am in hill country, I am always in tow/haul.

When you use the T/H button it will increase the engine rpm, on my rig it changes just under 600 rpm. I watched today to verify that it is locking out the 6th gear and will let the shift points go farther before any upshifts. When I'm rolling on what would be a flat I shift it off, to lower the rpm's. Any grades or hills, before I hit that incline, I shift it back on.

A motor home is always “hauling”. Nothing wrong with using it all of the time.


I called the Ford RV hotline and asked their opinion. They agreed. Since most motorhomes are within 10% of max vehicle weight when loaded and also when towing, they recommend using it all the time. They also recommended schedule 2 (severe service) maintenance schedule.


One of our members has a transmission temperature gauge. He says when he's in tow haul the trans temperature is much lower, so he uses it all the time. I think that's a good idea. Lower trans temp usually means longer transmission life. I use it all the time and it's so nice, particularly if you need to slow down quick;tap the pedal drop a gear then repeat.

I had the 5 star tune in my V-10 Excursion with the 4 speed auto. it made a world of difference in how it towed the trailer. We now have a 2012 class A with the F53 V-10 and 5 speed auto. the tow haul is amazing in how well it handles the V-10 and the weight of the MH. I tried it with and without. without it shifted normally, but I was on flat ground in the Midwest. I was also 1500lbs less than what I would normally weigh and no toad. I`m sure I will always be using T/H. whether or not I want to get 5 star tune has yet to be determined. I`ll wait till I get some miles on it before I decide.
