We were there a few years back and it was at least as nice as any RV park we have ever been in. Even Cell coverage was tight, but the showers and the other things were just great. It was not to tight for us with our short class A (not that different than your TT). There was talk that they may fix the cell issue.
The best part was that when you wake up you are already in the park. Just about across the road is the visitor center. You need to get there to the (sort of) geyser schedule. Sort of, because they are just good guesses. Take binoculars for everybody, good walking shoes, hats and water bottles.
We plan to go back even though we are now too old to do all that much hiking as we would have liked.
