This has become our go-to brand for maintaining the tanks in our 5th wheel camper. We’ve used several products over time, but we keep coming back to this one because it’s dependable and does exactly what it’s supposed to do. The drop-ins are super easy to use—just toss one in and you’re set. We’ve had no issues with unpleasant odors while using these, even during longer trips, which makes a big difference when you’re living in close quarters. We trust this brand and their products, and it’s one of those items we make sure to always have stocked before heading out.

Not the best of scents for an RV Toilet Tank

Scent: Lavender, Size: 30 Count (Pack of 1)

I don't know why I thought the scent of lavender would be great for my black water holding tank, but it's not. I'm sorry to say that I will have to return it. There's 30 Camco toilet 🚽 treatment packets in this container. All you have to do is just drop one of these packets into the toilet and flush it down into the holding tank. I am not saying that this product is not good; I'm saying that I will have to exchange it for a different scent. I won't know until I try a different scent, because I might be allergic to Camco's RV Toilet Treatment Drop-ins. The lavender scent put out such a bad smell, I couldn't breathe all night last night. I had to keep filling up my tank, waiting for awhile, and then dumping it all out. I had to keep doing that till the bad smell went away. So I'm gonna give Camco another chance, and try a different scent, and just go from there. I should have known better than to use a toilet treatment that had a perfume scent. I'm allergic to fragrant's, I have to use fragrance free laundry soap.

Solid, Reliable, and Makes the Gross Job Way Easier

Style: 20' Rhino Sewer Hose

Solid, Reliable, and Makes the Gross Job Way Easier This is hands-down the best sewer hose kit I’ve used. It’s sturdy, easy to connect, and doesn’t feel flimsy like some of the cheaper ones. The clear elbow is a lifesaver because you can actually SEE when everything is done (which every RVer knows matters). The hose holds its shape, stretches exactly as needed, and packs up neatly. If you’re full-time or travel often, this is the one you want.
