The Mingo RV Park is the closest you will get to Broken Arrow. The Expo Center park is more of a commuting hassle, you will be a couple of miles to the nearest expressways.
There is nothing in the area that is RV Resort quality. There are some places in the northern park of the Grand Lake area (around Grove) that are pretty nice, well run, but nothing special.
Rving style in NE Oklahoma tends more in the direction of actual camping, mostly outdoor living, and the public campgrounds are a lot more popular than the RV parks, which tend to be parking lots in feel, and are often filled with people who are in the area for a few months to a few years, because they work. The presence of people who work tends to make for low ratings from recreational travelers.
