Commonly called the Blue Boy or brand name Tote Along. This tank,(approx 25 gal) on wheels is for transferring your black water in an RV to a Sani Dump. It is brand new and never used (I wouldn't bring it into my house if it was used.) We bought it and never needed it. The marks on it are from duct tape I used to keep the pieces together so they wouldn't get lost. It has the hose and an extension handle. (Never used.)
