I recall air tabs were heavily promoted about 10 years ago, yet I have not seen a single one on the road.
My take is that would they really work, truckers would jump on them like crazy.
Even 1% in fuel saving for trucker means thousands of dollars every year.
Small percentage of semitrailers have rear shields, making it aerodynamics, but quite often I see them closed, so the same conclusion as above.
air tabs do work, but people expected miricals. there not going to get you 5mpg on a highway tractor and most people don't pull the same tractor all the time. so investing the 2-300 bucks to do a trailer is like throwing money a way as you might tow it every 20-40 trips unless you are the owner operator who owns his trailer. I have seen them set up on some RV's but some dont want them on there because it looks different. my buddy has them on his truck and camper but the camper never comes off the truck so he has them on the back edge of the camper (sides and roof) and then he has them ontop of the truck roof to disrupt the air as it hits the camper. he said he gets almost the same milage as before he bought the camper with a load in the box. so they do work. another thing for highway tractors is most are company drivers who dont care about fuel milage, infact the opposit. they just care about getting where there going fast to make more money on average.
