Walmart Supercenter

Large parking lot with back row right against I-10, so it can be pretty noisy throughout the night. The elevation makes Mexico partially visible in the distance (I could see La X statue). Many various trucks, RVs & campers park there most nights, so there's a risk all spots might get taken up by RVs covering a dozen regular car or van sized spots. Bathrooms, a deli, and McDonald's inside, subject to their own varying hours of operation. Bathroom cleanliness the best in the early hours after the morning staff have cleaned up.
