We planned a short overnight stop here on our way to Ouray. It might be busier in the heat of the summer, but we had no problem getting a reservation over Labor Day weekend. All have large flat pads and the campground has great amenities, showers etc. Very well maintained. Loop D has electrical hookups.
Downsides: It's a bit baren, with no shade and views of your neighbors. Our site was far from the water.
