I would like to see how it would do on a longer trip with more highway miles. Should be able to get about 10 mpg on a longer trip. The way home I did hit 75 a couple of times and that is when I started to feel the trailer move a little, brought it back down to 67-68 and it was fine. No problems when I passed the semi and did not feel any cars pass me either. Used the Tow/Haul mode the whole time and had the sway control off too.
I've been reading alot where guys are turning the sway control off. I haven't had a need for it yet (only been pulling my flat bed trailer) but curious if it just feels "unnatural" for the truck to correct itself or if it's due to poor design.
