I have stayed in Food&Fuel rest-stops, both Hy-way and private owned, from Jersey to Florida with no problem. I have stayed at restroom/vending machine stops on most toll roads with no problem. But some have gates across the entry with clear signs posting closing times. Those have a separate area for Big Trucks. I haven't tried staying there. Years ago I had no problem across USA or Canada. But today there are just so many of us.
