Truck pulling to left

[oilslick]

Hey guys, I have a '17 Rebel with airbag suspension and do a lot of highway driving. A while back at @ 9K miles, I noticed my truck pulling to the left while it's in aero mode at around 65mph or greater. I took it on different roads just in case it was the crown of the road making it pull. It wasn't. It still pulls whether the road is crowned on not.
I took it to the dealership (three times) for an alignment and they claimed that they finally fixed the issue. But after driving it on the highway, it still pulls. BTW, when it's in "normal" ride height mode at lower speeds, there is no noticeable pull.
Anybody have this issue?

Mine had a pull to the right but not sure if it was in Aero mode or not. Wheel alignment under warranty fixed the issue.

My 2010 did that, but found it was my brake sticking on the left front.

Sorry, i forgot to update this. The pulling was caused by the slightly wider aftermarket wheels. The pulling stopped when I put the O.E. wheels back on. Weird.
