In the market for a 99-07 chevy/gmc single cab short bed (rcsb) 2wd..... I'm looking for one with a 5.3l .... I've always wanted one. It will be a commuter vehicle for me. Driving 55-70 mph about 80-90 miles a day for 3 or 4 days a week.


My question is, what kind of gas mileage can I expect? I would ideally like to push it to 22 mpg. I know this is a bit of a stretch. What speed, air dams, tonneau cover, etc... can I add to achieve this? Will a 4/6 drop help at all? I plan to add a 4/6 drop either way. What wheel/tire size will work best? Will a 4.3 or 4.8 be any better? My thought process is that a bigger motor wont have to work as hard.


Any thoughts or suggestions are appreciated. I know this is not the best "commuter" vehicle but I'm currently driving a v6 tacoma 4x4 getting 16-18 mpg.
