We have been into some tight stations, Even once had to back out into the city trafic in Seattle. Sucks. That was the last time of thinking just one more exit. And believeing a sign that said "Big rigs welcome" Guess it meant we were welcome, just not easy to use. Also had a Pilot that the car section was worse than you could immagine. So do not just go by name plate. Their truck area out bak was great. Just not allowed out there.
We also look just entering or leaving a city. And we once tried to use a OTR lane in oregon and were told it would be extra. Also those pumps are big, lots of air in the diesel in your small tank.
Diesel is not hard to find anymore. Watch the trucks, or farmers, maybe even get a CB and ask the people in the area.
