We pulled off I-10 to stay for the night on a cross-country trip. This park is just off the exit and you drive through the gas station entrance to get here, but the park is remarkably quiet and scenic for being in the middle of the desert and right next to the highway. We arrived around 4:30 pm on a Friday and the office wasn't open. They have a dropbox that tells you to find a spot and pay the nightly rate in the dropbox. The restaurant is closed, but if you need anything at the gas station, it is very close. For $20, we have water, sewer, and electricity.  The T-Mobile cell service is amazing, but there aren't over-the-air TV channels. The sites are a little close together, but the first half have pretty desert plants between each site. There are clearly some long-term residents, but we felt safe and welcome and would definitely come back as a stopover.
