We just came down I35 to Texas. Stayed at Kansas City East KOA, Air Capital RV in Wichita, Oklahoma City East KOA and are now at North Texas Yogi Bear in Burleson (just south of Fort Worth on 35W). All were easy in and out with a big rig.
Both KOAs were 13 to 15 miles out of the city but traffic wasn't bad. Both had construction at the freeway entrance/exit but was not an issue.
Air Capital is right off the freeway and in Wichita city. Several restaurants in walking distance. It is a RV parking lot more than a campground.
Yogi Bear is both a campground for bringing kids that has pull throughs and they have an 82 site parking lot for RVs (all back in on concrete with patios).
