Using "tow/haul" function on Ford Triton
My 2016 Winnie Vista has the tow/haul option on the tranny with the Triton V-10. I understand what it does, question is, when do you put it on..while moving, while stopped, and if when moving, should ...

Always use Tow Haul when you are towing {hence the name} but even if you are not towing the weight/load of the coach itself is more than enough reason to use tow haul... all of the time. Add a scan Gauge {or similar product} that gives you transmission fluid temps and you will quickly see the immediate benefit of using TH.
Occasionally I forget to engage TH and as soon as I encounter even a slight grade the trans fluid temp starts climbing. Happily I usually notice the Scan Gauge display and quickly correct by engaging TH. The temp will drop 12 - 15 degrees in just a couple of miles as TH locks up the torque converter eliminating heat generating friction.
Engaging TH accomplishes several things, all of them good. On steep climbs the shift points are adjusted for greater efficiency. As noted above on long downhill grades you can let the engine braking control your descent. A typical 6 - 12 mile 6 to 8 percent grade often requires zero brake pedal application and you are not burning a drop of fuel all the way to the bottom where you arrive with cool, fully functional brakes.
The impact of using TH on fuel economy is insignificant given the performance and safety benefits, many even report improved fuel economy. Sadly, the Tow Haul function is often neglected, misunderstood or just plain ignored... TH is your firend.
