i did quite a bit of searching here and didn't really come up with the answer i am looking for. my truck is an 84 mazda b2200 diesel that usually gets about 30-35 city and upper 30's highway depending how slow i go, i haven't done any areo mods yet but here is my first opportunity. A stock aluminum cap for my truck popped on craigslist for 150 bucks yesterday but i'm not that interested in a cap unless it increases stock mpg more than just 1%. The cap is only about 125lbs. so the question is will a cap that is flush with the cab increase mpg's enough to make it worth buying?
