Has anyone here tried Airtab vortex generators on their toy hauler? A couple weeks ago we were on a very dusty gravel road and with the big vacuum created at the back of the trailer it sucked dust in ...
I do not have a toyhauler,but I have AIRTABS on my Class C.
They really help on a cross wind situation,no more sudden buffeting. It has stopped the sideways push when being passed or passing a large truck. As far a mileage it did not seem to make any difference.
On my trips to the High Desert here they made a huge difference on the dust collected on the rear of the RV and it seems to keep the interior cleaner after their install.
