I downloaded their "app" and saved my favorite stations that have RV dedicated lanes.( Mostly at the FLying J's vice the pilots.) My only gripe is I have no idea why they design the stations so the pumps are perpendicular AND close to the Store/building vice being "off-set" and a little further away.
And in short, yeah..an island with GASOLINE in the trucker area would be a nice add on for RV's. Probably wont happen due to tank locations and having to run a lot more piping.
We also have a "travel log" that we keep notes in on gas stations. Ive found some ones with fantastic maneuvering space, and don't want to forget where they were.
