My favorite site is 20E at Bluebell. It is towards the back of the campground (nothing but park behind you), well spaced from adjoining sites. It is a back-in site but will only accomodate a trailer up to 25' so it may be too small for you. If you go to SD GFP | State Parks | Directory | Custer State Park | Campgrounds | Bluebell you can see details on each individual campsite including photos of each. There are larger sites 22E and 24E just up from the one we stayed at that also back to the park and are 30' and 44' respectively. They have electric hookups, full bathrooms that were very clean and well appointed. The campgound was very quiet and peaceful. We had our water tank full when we arrived, there was water available but I don't remember if you could fill tanks or if it was hand pump style. Since we didn't need it I didn't notice....
Thank you for the great info! We are truly looking forward to our trip!
