Amateur. I once drove from Raleigh NC to Road America in WI with one bladder break.

Air Tabs DO actually work, but they have to be combined with other efforts to really shine. By themselves, their benefit is very minimal.
On the toterhome with the Air Tabs on the back of the toter and a Trailer Tail on the back of the trailer, we got ~1mpg improvement at our usual cruise speed of 68mph. Doesnt sound like much, until you realize that we went from getting 6.2-6.3 to 7-7.1 pretty regularly.
Also, someone mentioned the gas pump limit. Funny related story: We stopped in Dayton OH one year on the way back from Road America. I hit the diesel pump and headed inside for a snack and drink. Came back a few minutes later to the pump finally kicking off at 176 gallons of diesel. Needless to say, diesel pumps dont have limits.
