New 2023 Tundra owner with several questions

Getting 19.1 Combined through 420 miles on my latest tank with about 60% highway on my 2023 TRD Pro Computer calculated so it may not be accurate. Should be able to get another 100 miles on this tank before 0 range on the display. I drove conservatively around town to get this MPG. Highway was 75-80 mph. Last fill up was 17.5 mpg and with 4 miles left on range I filled up with 28.44 gallons.

I don't know if it had an effect on MPG but before my current tank I realigned my vehicle as it basically came from the factory not aligned. How you can manage to have camber and toe completely different on both front wheels from factory is a mystery. One wheel had tow in, the other toe out and the difference in camber was .6 from side to side which had to affect mpg at least a little.

Set lane keeping sensitivity to the max to stop the pinging back and forth within the lane.

 

23 limited double cab TRD OR, average 19-21 MPG running empty. 10-12 MPG towing 29 ft camper or 16 ft enclosed utility trailer. Lane centering...meh... kind of sucks when coming up on road construction and have to cross lane markers and steering is fighting back.
