While I have not noticed an overall change in quality, I will say that I've been in a couple of Flying J's where the RV lanes were pretty poorly laid out. I haven't been to one with my new coach yet, so I still can't judge on a Class A/toad basis, but I did run into some tightness issues with the pickup/5er.
I think that they would be better off eliminating all parking adjacent to the RV lanes.
I find that as long as I go nice and slow and pay attention to the car-driving lunatics, that I can generally maneuver through most any station.
