As others have said, Ft. Desoto is very nice but you will notice all the scares on the tress around some tight turns. I wish they would take some of the tress that are on the corners of tight turns and corners of the sites out. It would do nothing to diminish the beauty of the park but would sure alleviate some issues. We usually stay there once a year and I haven't had much trouble with height, but you have to be VERY careful with the trees going into your site. Several of the sites had a tree right in the middle of the site and you have to go to one side or the other. Also watch out for stumps as the few trees that have been cut, they seem to not cut the stumps down low enough for some rigs.
We always stay in the pet section which (in my opinion) is not as tight as some of the other sections.
