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.
