We stayed there towing a 20ft trailer. We were able to fit in two regular parking spaces between cross aisles, so pulled straight in and out. If you're longer, maybe you could park near the back fence. I didn't see anybody longer than two spaces ... maybe 38-40ft.
Probably not and you will be charged for all spaces you take up in the parking lot. It’s a tight squeeze making it through the lot for larger rigs. Good luck and have fun!
