If I'm towing and it's hot out I'll leave it on the trans temp. If im on a trip I'll glance at the fuel economy but then I'll turn it back off. I've noticed if I leave the fuel economy on then it goes down LOL so I dont watch it.
Drove from Orlando to Dickson, TN friday night and had trans temp up about 99% of the time. Had about 750-1,000 pounds I was hauling and the trans temp never went above 150 deg F. It did get into the 160's when sitting idling, but that's expected. When moving it was between 140-150, and it was about 70-75 deg F outside. I was pretty happy with that, I also have a 2,800 stall converter. I was also happy that my avg mpg for the trip was about 18.5 mpg, and the truck had plenty of power, I had it on the 87 SC tune, pretty much never even had to downshift out of 2nd OD going through the mountains. Maybe one or two times it did, and then I just put it on tow/haul for those steep areas.
On my 2009, i change screens easily, just a click or 2 with my left thumb, using the down or up arrows
there are control buttons on both the front & the rear of my steering wheel
most all of them just control the radio in 1 way or another
I usually clear out the EVIC, so the only thing showing is the direction of travel of the compass, temp, and the radio information.. but if I am displaying any of the screens it would be the fuel economy for the most part, unless I'm towing something then I'll display the engine data!!
