The tank design does not change nor will the issue go away with a newer truck. The truck has about a 50 mile reserve capacity to keep you from being stranded, I kinda like that.
You have to admit your knit picking pretty hard here, especially since Wisconsin doesn't have any mountains to drive on where it might actually make a difference.
If you want an accurate gauge ditch the hot dog tank for a fuel cell.
FWIW, I run an ultra-guage and it counts gallons left and current mileage. Also I have gotten just over 19 in my truck so you are not trying hard enough. I might be a bit hard on you but its honestly a small issue.
