Check your calipers for drag after release, they're famous for that, my rr is showing signs.
That funny you mentioned it. I did re do my brakes in 2016 when I bought the truck. needed rotors and pads very badly and I cleaned/greased the caliper slide pins. I do check brakes every 5k when I change the oil/rotate the tires. I haven't seen above 19mpg in a while though. I got 19.5 with stock tires and no front leveling kit. but the tonneau cover helped more than I ever thought.

Does anyone have any data on those roof mounted wind deflectors? see them on big rigs but rarely on trucks pulling 5th wheels. I could fabricate one pretty easily and anyone can ask my wife I don't give a rats butt about what others think my truck looks like lol. shes nearly pristine for 20 yrs old.

I was thinking the wind deflector on my roof because the side my side may sit 1.5 higher on even my new trailer etc.

I didn't know how valid the picture attachment really was etc.
