We were just there 7/13-7/20, and I didn't see any, but we also didn't tour the entire campground. We were in the 1300 loop. We had one coach on our loop, and it had to back in. We have a 31 ft class C, and all of the sites on our loop looked pretty easy to back into.
Just returned last Sunday from FW and toured the entire site on bicycle. There are no pull thrus and do not feel they would convert any sites to pull thrus. We get our FW fix once a month and will keep an eye out for any changes.
