We went in June this year and stayed in three different parks. We only had hookups at one park, Fishing Bridge. It is helpful to have LEDs and make sure your truck will charge your batteries while you drive. All RV parks in Yellowstone are expensive, but I liked being in the park. Truck Campers aren't allowed in Tent Spaces. They have length limits for some spaces. If you haven't been to the Tetons, you might consider going through there as well.
Read up on having dogs there. They are extremely limiting since most trails don't allow dogs and only relatively short leashes are allowed. Many of the side roads don't allow RVs. This is a conflict if you bring the dogs with you it generally means you will have your TC with you as well. Old Faithful has a schedule. Look up the schedule before you plan the trip.
Early AM and Late PM are two of the best times for spotting wildlife although they can be seen any time of day. I didn't have much of a problem parking in most areas. There are some pulloffs to fix a meal, so we did that instead of cooking in the campground.
It is high elevation with almost all of the park is over 7000 ft. If you use a Keurig, look up how to use it at high elevation. Some fridges have issues at higher elevation, but we didn't. Gasoline and Diesel and supplies is pretty readily available in park.
Bridge Bay - We liked walking the loops a lot because we like to walk a bit after meals. You can see a tent just off the left of the front. No shade on this one. They call it a pull through, but it's more of a pull off.
๐Grants Village - there were some back in spots. That little red spot to the left is one of the tents from our neighbors that had two small tents and two Harleys. No other vehicles.
Fishing Bridge - this is similar to the spots you see along the interstate as you can see. The roads were curiously really potholed. I found it funny that the one with the full hookups and more expensive was in worse shape. Not a problem ... just an observation.
