Rest areas along I-75 usually do not have signs indicating the location of the RV dump station. Instead, you should look for signs directing you to the truck parking area. The RV dump station will be found at the exit of the truck parking area, but there won't be any signage specifically for it. It's important to note that there is no water available at the RV dump station located at I-75 Milemarker 319 in the southbound direction.
