Happy Campers RV Holding Tank Deodorizer

I bought this a few months ago for $60, and recently sold my RV. The original package weighed 4.6 lbs, and now weighs 2.4 lbs. This is the best tank deodorizer out there, in many people's opinions. More than half is left... yours for $15. : ) About this item: RV holding tank deodorizer: This RV toilet and sink treatment has no added scent and is specially designed for RV holding tanks, providing powerful and lasting odor control for both RV sewer tanks and RV gray water tanks.
