I have a 35ft 2014 f53 chassis. I have never used the tow haul mode but once and didn't much like it. Do any of you run it all the time? How does it work going up hill? I tried it going down hill and ...
I'm a convert on tow/haul. I used it only in the mountains for years because I didn't like the shift pattern. Used it for the additional "braking" op mentions. Then, when riding with a tow truck driver with my car on the hook, noticed how much it helped when stopping under load. Tried it again next time I towed. No difference in mileage, and love the extra stopping assistance. Now I use it every time I tow, no matter the grade.
