I just came down I-75 through MI, OH, KY and TN and OH seems to be the worst. One exit I had tried 3 stations and had to get back on 75 and go to another exit. I disagree that "most PFJ's have dedicated RV lanes, I have seen only one in my travels. I have heard that Love's had dedicated lanes but the ones I tried, 2 of them, this trip didn't.
I can agree that the secondary roads are more accommodating in gas station offerings. I can maneuver my rig just fine too thank you. I just find it irritating that gas stations can't bring themselves to provide just 1 pump to accommodate the RV community no matter what the numbers are.
