We went to SD this August and saw all these things except Wounded Knee (though we went by Wall since it is right by the west entrance to Badlands NP). We stayed in Custer (the town, not the SP) at an RV park and did day trips for all. I am not sure Devil's Tower is worth an overnight stay, unless you are hiking around the base. We stayed 6 nights at Custer. All of these are easily reached by drives from there. Devil's Tower consumed a day since it is about 110 miles from Custer. You might consider one relocation up to the Deadwood/Sturgis area to have a closer base for the Devil's Tower trip.
Mount Rushmore is worth seeing, but does not consume an entire day. We saw it the same day as Crazy Horse.
Given more time, we would have probably spent it at Custer SP or visiting one or more of the caves/caverns in the area. The wildlife loop, the Needles Highway (check tunnel clearances) and Sylvan Lake are the must see items, in my opinion.
I admit my bias may be that I come from Texas where 100-mile each way round trips in a day are not out of the ordinary.
