I have generally found Flying J's to have the lowest price and little problems at the RV islands. On our last trip did stop at South Beloit, EXIT 1 on I-39. Old guy in Motorhome completed filling then went in to pay before moving out of the way and then when he came back he decided to dump
. I kept my cool, but I was tempted to get out and ask him how long he had been RVing and did he normally act like an idiot. But life is too short to let people like this get on your nerves. Because the Dodge can take the larger noozles I will pull into the truck islands most of the time. I am carefull to pull out of the way before paying. I did have one experience when a trucker blocked my exit as he did paperwork.
