We were out in Fishing bridge in July for 6 nights. The sites are definately NOT all the same size. You will not be able to put a 36 footer in a 32 spot. The slots get longer as you move out on the arms of the campground.
We reserved a 35 foot slot for our 33 foot trailer. We backed the unit in as far as it could go, the tongue was right on the edge of the road. We could not open the awning (another tree) and the kids got a kick out of our slide opening up right next to the slide on the camper next to us. We could literally see what they were eating for breakfast.
The spots are VERY TIGHT but the location is central and will save a great deal of drive time.
