I honestly don't care about any of that when I'm needing diesel. I just want a station where I can fit and maneuver and won't have to back up, since I tow four-down and can't back up. I know I'll be able to do it at truck stops, but in some areas I have to use regular gas station (and gas RVs can't use truck pumps).
I also know it's extremely unlikely that I'll have room at a regular gas station to park and walk my dog or use their internet, plus there are other sites that have that sort of information.
I looked at the gasbuddy RV-friendly site and the comments that people put there are helpful, but only kind of.
I looked at one that said, "Very clean little store with great access for RV's." Here's the street view of that location:

There is one set of pumps in front of the store. They are parallel to the store, which is good, but with only one set of pumps, you have to be on a particular side to match your fuel filler and a rig 60+ feet long will be taking up a lot of space there. I would mark that as "do-able" for me--definitely not "great."
Another one said, "Easy in and out for big rig RVs" Here's a satellite view of that location:
https://www.google.ca/maps/place/1401+Coors+Blvd+NW,+Albuquerque,+NM+87121,+USA/@35.1000405,-106.7081539,113m/data=!3m1!1e3!4m5!3m4!1s0x872272b1037f8295:0x8c70a1509bf41372!8m2!3d35.0999898!4d-106.7081664
Maybe I'm a weenie, but I wouldn't try that in my RV unless it was the middle of the night, and even then, only if I had to.
I think this will be an issue with any site that relies on what people say about a location. But I would use the site to get
leads on places that
might be big-rig friendly that I can research further. I would never just use the app to tell me where to go, even with people's comments, like I might in a car.
But I still see a problem for gas coaches, who can't use diesel/truck pumps. Maybe force users to say whether their comments are for diesel pumps only? I think a station with a separate island away from the building with truck pumps is ideal, but that doesn't do any good for gas RVs.
