Currently working on replacing 27 year old toilet system on my E33. Planned to reuse holding tank, until I found several cracks around collars where intake/ exhaust fittings attach to tank. Big bummer. Surprisingly the original manufactures label was still attached and a part number stamped into tank. Ronco Plastics Tustin California STILL IN BUSINESS! STILL HAS MOLD AND DRAWINGS!!! Excellent customer service by employee named Rich, excellent price $120!! 25 gallon odd shaped box. Tank should be here in about 10 days shipping to Maine UPS ground. Ronco`s phone is 714 259-1385. Quite pleased!
