At the sites I stayed at no. Maybe down at the roundabout at the end of the gravel road if it wasn’t full. The parking lot by the entrance says “no overnight parking,” but I saw a couple in an RV about that size stay for two nights if you want to chance it. Alternatively, about 5 min driving past the entrance there is another meadow with several sites that I saw some large trailers park in. I did not enter though as it was close to a main road, so I did not personally view the sites up close. Good luck!
