Rest areas along I-75 usually do not have signs specifically 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 situated at the exit of the truck parking area. However, there may not be any signs indicating the dump station itself. Please note that the rinse water available at the dump station is not suitable for drinking. Additionally, the water supply may be turned off during freezing temperatures. The specific location mentioned is at Milemarker 47 on the northbound side of I-75.
