This. Monitoring operation and quality of fuel from brands and stations is why I watch mine. Hell, I noticed the .5-1 MPG I lost with the recent installation of the 22s. Only getting 19.xx at 80 MPH now. :rolleyes:
:D

Mine is always on miles till empty.
But I do reset the trip every tank and as I scroll through it's often only around 8.5.

Today i drove 2h one way to put on new wheels and leave old bad ones to avoid paying any duty on my way back at the border.

Rides smooth with air rear, i don’t feel difference with the old 20s

Edit: wont let me upload pic, will do later

mine is the 6.2 AWD I don't see nearly anyone getting any worse mileage than me, what is your setup?
any type of lift and those 33"s will put a hit on it

The front end is 3 in higher than stock.
The 33s are only a tiny bit bigger but yes definitely don't help.
I've got the truck towing mirrors on it, and the "border patrol bumper cut"
Plus hundreds of pounds of crap in the back at all times.
Oh, and e85 all the time.

My new mirrors heat functiion is not working. :( I see the wires going to the back of the glass. Even used a temp gun. I guess these run off the fuse for the rear defogger? I will check that.

Fuse was missing. I replaced it but still no dice. I hear the relay kicking in and I have power through the fuse. Guess I'm gonna have to check power in the door harness at the mirror switch and compare the plug on the new mirror to the old one I saved. And check wire colors etc.
