CamcoRhino 15-Gallon Portable RV Tote Tank - Features Large Heavy-Duty No-Flat Wheels & Low Drain Hole - Includes Removable Steel Tow Adapter, 3’ Sewer Hose & More RV Accessories (39000)

Very sturdy. Easy to use without touching contents. Came quickly and better price than others.

Being nowhere near a sewer, I really NEEDED something like this. Works so well I bought a second unit and that makes THE CHORE much easier as I can stow and dump at my leisure

Better than expected. It has great deals that virtually eliminate the smell of emptying your tank . It is easy to tell when it's close to full, but I highly recommend buying the pressure valve attachment that tells you when it's full . The cost is high but considering I was paying a septic company $115 every 4 weeks to come empty my tank is will pay for itself in just a few months. Camco provides all the necessary pieces too seal it off. If you are paying to have your tanks emptied on a monthly basis I would highly recommend buying one of these just because you can empty your own tanks as needed and the money you will save by doing so is enormous. My only complaint is the wheels are a bit chintzy it would be a lot better if it had steel wheels and rubber tires it would make moving it across uneven ground a lot easier. That said it's really not that bad

Purchased it to use for gray water when not at a site with full hookups. Works well. 28 gallon capacity works good enough for us, but we are in a pop up with a shower and sink that aren't used a lot. Our toilet is a cassette so that eliminates the need for black water storage. If you had bigger usage needs, a larger tank may be a better choice, but you will know your needs by how much you use the systems in your camper.

UPDATE: Have used the Rhino on about five (5) family camping trips during the Summer of '21. It has worked flawlessly and couldn't be more pleased. My only gripe is the lower quality wheel/axle assembly as compared to the tote itself. This is a solid 4.5 Stars and will be hard to beat for the price._______________________________________________________________________________________Purchased this for a Class A RV with a 50g fresh, 44g gray, and 24g black. Few considerations/observations:1. Never get a tote that holds LESS THAN your black tank if possible. Even if you are only planning to use it for your gray, you never know when you may actually need to dump the Black & you definitely Do Not want to go over.2. How are you going to transport this when empty? The Rhinos have a good solution for a ladder attachment, but other brands do not, and what if you do not have a ladder? Things to consider.3. Water weighs 8.3 lbs/gal. The 28g & 36g totes are going to weigh approx. 250lb & 325lb when full including the tote. If you are getting those, I would recommend getting the variant with the 3rd front wheel unless your name is Conan & have a good chiropractor.4. The Rhino's 3" inlet sits higher than other brands especially for the 28 & 36 gallon versions. Attach the provided clear elbow & that adds a few inches as well. You are at about 14-15" off the ground. You will have to get creative with the discharge hose, dig a hole for the tote to drop a few inches or figure this out by some means if your RV outlet is lower. Just something to be aware of which may or may not affect you.5. For the 28 & 36 gallon versions equipped with the gate, just know that all dump stations are not perfectly level & accessible (in fact many are not) so presuming you will be able to pull the gate and water will flow perfectly into the drain is not always possible. Add a small curb found at many NFS dump stations & you may need to tilt the tote to create a gravity posture. Good luck with the big totes (refer to Item 3). This is where the totes you lift to empty like a wheelbarrow have a clear advantage if your back can support it. [Update: you can also lift & dump using the 3" opening on top if needed if the gate opening is a problem...pushing it up a star]6. The wheels are basically hard plastic and the axles are capped instead of secured with heavy duty cotter pins. There is a YouTube video that describes this tire axle/tire weakness. The YouTuber's solution was to remove the caps, drill small holes in the axle ends & insert rigid cotter pins to prevent the wheels from coming off. If you are towing around 250 lbs to 325 lbs, can't understand why they would only use cheap axle retaining caps. [UPDATE: Rhino has addressed this with recently released versions. They are cinching improved caps over the axle end to help prevent the cap from coming off. Hopefully this will help].So, because of the new observations & wheel improvements, I'm giving this a second chance with a smaller 28 gal; IMO, the 36 gal is too heavy for that wheel assembly. Overall, Rhino has some nice features like the backflow valve & the cleaning spray mechanism when you attach the hose and it is clearly a solid product (minus the wheel/axles). Great accessories as well so can't beat that. Going on a one week boondocking excursion & will report back.

Seems very well built. I have used it twice, no issues. It fits under my trailer, is short enough to take outflow from my black water, but I also have 16" tires on my trailer, so its a crap shoot as to whether it will have a drop from any other trailer or not.... for me, works great, easy to use and dump. Bigger in size than what my minds eye had imagined, but 28gals is 28gals....has to go somewhere. I can manage it empty to get it up off the ground for transport, but 8lbs per gal = 224 lbs of load plus the weight of the unit, most of us aren't lifting a loaded one.....(I bought a receiver mounted deer hoist that swivels to lift it up and swivel it into my pickup) anyway, glad I bought it, I do lots of dry camping hauling in water for extended stays and I hated having to leave with my trailer to find an RV dump. Now I can just load it into my pickup, leave the trailer at camp and head to town to dump... Life is good...

Works great no problems using, storing, dumping!!!!!

Pleasantly surprised that it was easy to lift and tote by hand. Came with all the hookups and seems pretty sturdy.
