Campgrounds near Yellowstone

As noted, Colter Bay is an excellent option for the size of your rig. If you have satellite, you won't get it in Colter Bay due to the trees, but the setting is amazing. Not to mention that there is a laundry, convenience store, gift shop, and restaurants in the village. Headwaters CG is another option, and used to be called Flagg Ranch. It is quite a drive from the East Entrance, but there are several RV parks in Cody, further in is Buffalo Bill state park, but there is only water and electricity, no sewer, but they do have a dump station. If you don't mind the drive, as we don't mind, there are a lot of options outside the park from the west side, south, and east. Many forest service campgrounds with electricity too. We often stay in those because we like the dry camping feel. Rex Hale on the east side, Falls off Togotwee Pass, and Bakers Hole north of West Yellowstone.
