I installed Air Tabs two years ago and I noticed an improvement in stability with cross winds and bow waves from trucks. Determining fuel savings is hard to do for a small improvement when there are several other larger factors contributing. The principle for Air Tabs is right and they probably improve MPG. The back of my MH is cleaner now. The appearance is up to personal taste. I don't mind the appearance of mine at all. The low cost and ease of installation of Air Tabs is a key factor for me. As fuel becomes more expensive things like Air Tabs become more attractive. BTW, slowing down proved to be the biggest factor in increasing MPG.
