RV Portable Waste Tanks: Decent, Better & Best

Waste – It’s a dirty subject. And we’re not trash-talkin’ here; we’re talking about the real deal. The kind of waste that belongs in a sewer, or in our case…the dreaded RV black tank.

But what do you do when the tank’s full, and you don’t have full hookups?

We’ve got you covered with RV portable waste tanks, from decent to better to best.

A Quick Story About RV Portable Waste Tanks

Whether you’re plugged in or boondocking (free camping), dumping your tanks is rarely convenient. Picture this: your RV is perfectly set-up, absolutely level, wonderfully lived-in with all your kitchen appliances out and about. 

Your computer and work gadgets are (chaotically) organized on your desk.

Most of all, you’re happy exactly where you are.  

Tank’s full.  

Instead of packing everything up and driving to the nearest dump station, you realize that you did a very smart thing the other day.  You purchased an RV portable waste tank.

Now finish binging your Netflix show!

What is an RV portable waste tank and who needs one? 

An RV portable waste tank is exactly what it sounds like.  A container to hold your waste (gray or black tanks) temporarily as you transport it from your RV to the closest dumpsite. 

These come in handy when you are parked at an RV park that has a dump station on site, just not directly at your camp spot.

When your tanks are full, you simply dump into the portable waste tank, wheel it over to the dumpsite, dump, clean, wheel it back to your RV and finish watching Netflix with the ease of mind that you may now continue to use your facilities without worry of overflowing your tanks.

Ideal for medium to small RVs. Let’s you extend off-grid camping without breaking camp.

What to consider when purchasing?

So how do you know what kind of RV portable waste tank to purchase? Simple, anytime you purchase something that is going to be kept in your RV, you probably go through a set of questions already, such as “Do I have room for this? Will I actually use it? Where will I store it? Is it easy to keep clean?”

Ask yourself those same types of questions to help you understand what type of portable RV waste tank will work best for your RV needs:

  • How big of a tank do I need? Consider your current holding tanks and their sizes, along with your available storage to determine how big your portable tank should be.
  • Where will you store it? Do you have space in your basement compartments? Maybe you need a smaller tank due to lack of storage space or maybe you have plenty of room and storage is not an issue.
  • Consider portability issues. Do you need a tank with wheels or do you have the muscles (or desire) to pick up 35 gallons of waste?
  • Remember, this tank is not your typical tank – it holds waste. You’ll want to be able to clean it without a huge hassle. Does the tank you’re considering offer ease of cleaning, and how easy is it to actually use? You don’t want to purchase something using your hard-earned money and then never use it because it is difficult to put together or take apart. You already have plenty of exercise equipment doing that job.
