I am trying to improve my mpg
as I'm about to start using it 100% of long distance travel. I'm currently getting 14mpg on its best day (no load). Towing is usually 7-9 mpg's pulling 7500#'s. Only 124,000 miles. 4.10 gears. When I bought it, it came with 235/85-16 tires (non OEM). 95% driven unloaded, 5% pulling a race car trailer. CC
Given, I have been reading quite a bit lately, especially this entire section of this forum....so...on with the questions.
Will a tonneau cover help or hurt or no change?
Will going back to the stock size tires (215/85-16) help, hurt, or no change?
Will going to 3.55's or 3.73's help, hurt or no change?
I understand a 203* stat will help at a minimum but will be getting one b/c it will help.
Any other mechanical improvements?
I also need to check on the brake situation...as my brakes squeek upon braking once they get warmed up.
