We have gone to Yellowstone 4 time over the years & have never had a reservation.
Yellowstone & Tetons An old post.
Any of the campgr'ds in the park, such as Grant, Canyon, Bridge Bay, Mammoth, Madison etc., would be ideal. It is a big place takes some serious driving to see the place. Much easier to do so in a more central location. Drop down to the Tetons before you leave, it is neat and somewhat different.

Site Clicky tells about each campground (down by "Click on a Campground Name Below to Take an Interactive Tour"), if the chart has DS for Dump Station in the Features column it has a dump station. Ha! Grant Village, Canyon, Bridge Bay, Madison & Fishing Bridge have them. One could use Mammoth or Norris (ones a generator can be used) & still dump in one of the other places.
The last 2 visits to Yellowstone was in July (2010) & Aug (2009). We stayed at Mammoth CG in 2009 & Grant CG in 2010. We have been 4 times all together & never had a reservation. Madison, Canyon, Bridge Bay as well as Grant & Mammoth CGs all should be places to consider. Checking the site given above should help on rig size. Mammoth has some sites which would work. There were really large rigs there. We came in from North Dakota in 2009.
South entrance via the Tetons is the easiest route into as is the North entrance by Mammoth. West entrance would be easy enough, but take a lot more driving to get around to it. East entrances one will have to do some climbing. We enter that way, via Cody, once & exited that way in 2009. Not too hard of a climb, very good hwy.
In the Tetons: Gros Ventre Campg'd or Colter Bay Campg'd. We stayed at Colter Bay Campground, the one without hook-ups in mid-June 2010 and once before some years ago. The Colter Bay Visitor Center and Indian ArtsMuseum by the Colter Bay Campground is really neat.
I have heard good things about Gros Ventre Campground...get more animals walking by or close by, etc. Nice views. (from French: big belly) Actually, the French used the term Gros Ventre, for a local native population/people which was mistakenly interpreted from their sign language. Instead, the Gros Ventre people call themselves by the autonym A'ani or A'aninin, which means "white clay people," or more loosely "ourselves, our people, us, we," etc. The French is pronounced "Grow Vaunt."
Both Gros Ventre & Colter Bay have dumpsites.
We stayed at Mammoth Campground for 2009 visit to Yellowstone. It has some very large spaces in it, almost any size RV could fit. But can't make reservations, but we have never done so in the four visits we have gone there over many years.
We stayed at Grant in 2010, pretty large campground, all sizes of RVs. Bridge Bay looked like it would be a nice one to stay. We did stay there in '86.
