I installed 76 AIRTABS (26 on each side and 24 across the top) on our motorhome, and then drove it across West Texas in very windy conditions for about 600 miles there and back. The change in handlling qualities was unbelieveable. The AIRTABS really calmed the sway reaction to cross wind gusts and passing trucks are barely (if at all) noticable. The coach felt generally more stable. All of this added up to a much more enjoyable and less tiring friving experience.
I found it difficult to quantify the improved fuel economy (i.e. an earlier trip with exact winds, loads, etc.), but it looks like i’m doing about 0.5 mpg better )our coach gets about 6.5 to 7.5 mpg).
Thanks for a great product,
