First off congratulations on the new coach. We looked at the Outlaw but went with the Challenger.
I struggled a bit because on those long stretches of roads I like to use cruise control (CC). If I set the CC at 65 or less, our Challenger would do the infamous downshift slam (sounds like all hell broke loose in the engine compartment). That will still happen on occasion but what I found is to set the CC at about 68 (at least for our coach). Then the CC will hold fairly well. Won't shift until speed gets down around 61 or 60 mph. That is what I refer to as our coach's sweet spot. It hurts my gas mileage a bit but I feel the tradeoff is worth the convenience .
Lots of owners have went with 5 Star Tune. I tried it and it was great except for when the CC was on. Then not so good.
There is a great deal of info over in the F53 Ford Forum. A couple of real good pointers in this thread at the IRV2 forum.

The Tow/Haul mode is really helpful. There are number of threads regarding the use. I use it downhill and in heavier traffic. The motor helps brake the unit and hold speed.
Again. Love the Outlaw.
