Three years ago I first encountered Happy Campers at an RV show. My initial thought was, “This is snake oil”. Regardless, I purchased some and tried it out. I will never go back to any other product! I was formerly using an enzyme, but discovered that enzymes stop working at high temperatures.
This summer I used Happy Campers in temperatures exceeding 100F. The product worked as well as it does in lower temperatures. When I empty my black tank there is no smell. Literally NADA. I also use it in my gray tank.
When you purchase a large tub, I estimate this product costs about 1/10th of a liquid enzyme. It is so economical, I no longer worry about waiting until I have a full holding tank before dumping.
We now recommend Happy Campers to all our members based on cost, ease of use, and environmental friendliness.
