We stop over at WalMarts & FlyinJs a lot traveling from one race to the other, just no time to look for a camp ground.

One city you dont want to overnight RV in, is Pittsburg PA, because you will be less than a third class citizen with LEO running you off from one place to the other.
It is a city law there, you can not park an RV & Enclosed trailer on any city street for any length of time, even to get out & check a tire or something else with out being issued a ticket.

We do it all the time. Flying J has spots for RVs in front of the station. We stay mostly at Walmarts. There is a list of Walmarts on the Yahoo Walmart Group.

Walmart RVing Invitation

We have stopped in rest areas, Walmart, truck stops, and even small town grocery store parking lots (with permission) for overnight stops.

You do need to be aware of restrictions plus possible crime... many cities have passed RV parking laws and some RVers have been accosted while staying in some of these types of overnight stops.

There is a website dedicted to free overnight camping spots...I don't remember the name of the website but I bet it has free and camping in the name.
