  • Pretty Good sized.....barely fit on the bumper tray I carry stuff on....
Size: 28 Gallon Style: Heavy Duty (2 Wheel)
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... ... show more

  • This is one solid tank, and great accessory bundle.
Size: 28 Gallon Style: Heavy Duty (2 Wheel)
Hate monitoring water usage when camping? Get this tank. Love taking hot showers in the comfort of your camper without having to walk a half mile to the bath house? GET THIS TANK. Hate having the park honey wagon camped in front of your rig? (louder for the people in the back) GET THIS TANK!! This thing literally saves marriages! Seriously though, this is worth every penny. It is extremely sturdy, but that does make it a bit heavy compared to other options out there. The horizontal (side) gate is a very nice option; you can leave the tank laying flat to empty it. It will be heavy when full, but it is still easy to maneuver courtesy of the very sturdy wheel set. The included accessory kit is a nice inclusion. I store it on the rear ladder of my camper with 2 ratchet straps (and a cable lock, since I store in an unmonitored storage lot). If I don't need it for any particular trip, it stay nicely out of the way on the back of the camper. The ONLY thing I would like to see improved is a slightly longer hose. If you are using the end drain instead of the side/horizontal gate, it is sometimes difficult to get the hose connected and positioned while also trying to lift the weight of the (full) tank. That's very minor issue, and given the horizontal gate option, I did not feel it warranted removing a star. ... show more

  • Solid Product - Few Caveats - Know Your Needs First
Size: 36 Gallon Style: Deluxe (4 Wheel)
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. ... show more
