Campground Near Wilmington, NC
The only place that we have found in the Wilmington area, is the Wilmington KOA. It is your typical KOA (an older one). The sites are level and the campground is clean. The bathhouse could use an update, but they are okay. Nice dog park. It is easy to access from Interstate 40. It is about 6-8 miles down to the Wrightsville Beach area. We have stayed there twice.
Don't know if you are willing to go a little further away, but 58 miles to the south of Wilmington in Longs, SC is the Willowtree RV resort. It is about 12 miles north of Myrtle Beach back towards Wilmington. This is the nicest RV park we have ever stayed at. We love it there. Woodall's gives it a 5 star rating and they have earned it.
