You sound just like my husband and I have to agree with you too. I have often thought that there should be a Forum here for good Gas Stations - sorted by State. I wonder if it could be done? Then whenever you find a good gas station you can add it to the list.
We have a Pilot/Flying J card and we use their gas stations whenever we can - and their App on the iphone will tell you where the nearest stations are, if they have dedicated RV lanes and if they accept the card - and a lot more. After using the stations you can also rate them and comment as to how good they are or aren't.
Loves gas stations also have a similar App and that is useful too.
I have also downloaded Trucker Pro App which tells me not only the gas stations around but also rest areas and more. We have used some Shell stations found on this App which have proved to be excellent.
Just a few thoughts....
