Also some good threads on RV.Net. I had them on our Bounder, liked what they did for handling, especially in shifting cross winds. The back of the rig, and toad, were kept a bit cleaner too. In rain, the rear camera was not as impacted. I did see some MPG improvement, but not the reason to consider them. If painted to match, they blend into the rig pretty cleanly.
We'll add them to our Allure in the future, when I get some other touch up paint work completed.
And yes, Airtabs seem to have away of sparking dialog
!
Good luck on your research,
