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.

Worth the money. Get it.
Style: 20' Rhino Sewer Hose
I am a full time RV'er and these are the best hoses I have worked with. At this point I just do not buy anything else unless I have no choice. Yes, everything fails over time but these last the longest. If you want solid equipment you just don't have to worry about, get these hoses.
