Only thing I’d mention is to make sure you pack it well - obviously as a soft bag it won’t hold its shape at 70mph, so you need to pack in a way that it will stay even, and it won’t start to lift and fold in the front of the roof.

Positive Feedback

Be prepared to lose lots of mpg with it on the roof.
