Making pit stops

I have a question for anyone who RVs solo. How do you make it across the country by yourself. Like do you make pitstops at occasional rest stops when you need sleep. Do you find somewhere on the way to sleep. How does one get gas while road tripping across. Do RVs people get gas from truck stops? Cause when I think about it, I don’t see many RVs getting filled up at the regular gas station
