We have a 2014 Winnebago(gas) with the Ford V10 engine. I tow a small Pontiac Vibe behind. When going down a long descent, I'm wondering what is the best way to go. I always have tow/haul mode engaged...
Where Tow/Haul really shines is when you get off an exit that is short and steep down to the stop sign. A few taps and it's really helps you slow down quick.
