We stayed a few nights at this campground in October.  The campground is made for smaller sizes but we were able to negotiate the main ring road with our 37' travel trailer.  The spot that we had reserved was in an area were we could not get into but we went to the gatehouse and they gave us another spot that was on the main ring road that we were able to park in with no issues.  Cell service was great with Verizon and AT&T service.  The lake was beautiful and the park was well maintained.  Wished the beach, paddle boats, and petting zoo was open...  Still had a great time.  We will surely come back next year when everything is open!!  Had 30 and 50 amp service with water hookups and a dump station at the exit.  Make sure you have plenty of leveling blocks.  We used all of ours and was not level.
