The RV dump station at I-90 Exit 61 is not your typical Flying J dump setup. Instead, it has a large hole cut into the sewer manhole cover. The RV dump is located halfway back in the truck parking area. Additionally, there is overnight parking available for RVs. You can find the RV dump station behind the dumpsters behind the convenience store. It is labeled as the RV Dump. Please note that the rinse water available at this station is non-potable.
