We were able to get in Site 7 with our 35'. I would not recommend any longer for that site. I would avoid Site 6 since it is not well defined and on a hill. You could fit a 35' and probably a little longer in sites 1, 2 and 3. Site 4 goes back quite a ways so it might be able to accommodate a little bigger rig and Site 5 is a little smaller. Take a look at the posted pics especially Site 4 to see how you think your coach would fit. The turnaround can also get pretty tight on the weekends when people park their trucks in the front of their coaches.
