^ Huh wayxm? Whadaya doo when yer not on an interstate? But thanks for the specific recommendations in Michigan, NY and GA...
To the OP, a few websites like gas buddy etc have some info.
Finding fuel is not something I've ever considered to be a chore, even when towing. Aside from inner city gas stations, I can't think of a place I've been with a trailer that worried me getting into.
Just take a look around as you're driving, bet 95%+ of non-inner-city stations you can pull right into.
Thank about it this way. Except for the rare instance, they all get fuel by semi trailer or b-trains.
Don't sweat it and if you are sweating it, just carry a jerry can of fuel.
