This is from Site 22 Notes:
Site
**The maximum allowable trailer length is always shorter than the allowable RV length (due to maneuverability). You are responsible for reading the site alerts and booking a site that will accommodate your equipment. If you arrive to the campground with different equipment than what you booked for, you will likely not fit, and will be turned away.**
The maximum trailer length allowed in this site is 18 feet.
That pretty much says it all.
Redo your 'search' for site with 27'....sites 20, 30 etc will accommodate 27' check availability then call and have reservation moved to larger site
