Pretty standard parking lot arrangement. There are large RV parking spots on the east side of the building, closer to the highway. I stayed the night with about 4 other rigs. There used to be and RV dump station but it's no longer there.

Stayed here for a night, they have overnight RV parking. It was full when I got there but I parked in the big parking lot and didn't have any problems

Stayed here one night while driving through. The spots by the water station were all taken, but was able to park in the larger lot with no issue. Several other vans and campers were in the lot as well. Make sure you have window shades, though, as it’s a parking lot with bright lights (understandably).
