Open for debate. They are mounted horizontally on the van, which makes them subject to almost no face-on wind forces at all. The aluminum frames are bolted to the van, but the van structure is metal and likely doesn't move much in terms of distances between bolts other than due to thermal expansion, which is also true of my ground-mount array (in the dry desert :)
There's more vibration on the van, but how the impacts their life compared to the months of daily 30mph+ winds hit the faces/rear of the ground mount array seems hard to tell without a lot of research (which someone may have done).
