BUYER'S GUIDE
Here are some key considerations to mull over before purchasing a portable waste tank for your RV..
What type of RV do you have?
Class A RVs generally don’t travel well where you would need a portable waste tank, and most owners don’t tend to park them anywhere but an RV park with a full set of hookups. 5th wheel trailer owners and Class C RV owners should definitely consider keeping a portable waste tank for their RV since they can travel to off-grid locations where there are no RV hookups.
What is your RVs sewer tank capacity?
You don’t need your portable tank to match your RV tank size, but you want to be able to drain away what’s in there in as few trips as possible.
What kind of terrain will you be traversing?
If you’re dragging this tank by hand over rough trail, gravel or broken asphalt, you may find some models work better than others. If you are going to tow it behind a golf cart or ATV, you will find the task and options much easier.
On an average trip, how many people will be traveling with you?
How often the waste tank needs to be emptied depends on how many people are using your RV’s toilet. More people means you need to drain that tank more often. The bigger the portable tank you buy, the fewer trips you’ll have to make, and if you don’t need to empty it as frequently you may be fine with a smaller tank.
Is There A Certain Size Portable Waste Tank I Need For My RV?
The size of a black water tank or a grey water tank is important from two viewpoints. The first factor is portability itself. There will be a big difference in how large a septic tank you want to transport. In particular, when the container is full of liquid, which can weigh more than 8 pounds per gallon. Some portable septic tank manufacturers address this by putting wheels on the tank or manufacturing a portable cart base so that the tank can be moved around without needing to be carried around. Having a dump station nearby can also be an important consideration if your RV's site is quite far from the nearby dump station. A wheel's material can also influence its performance. It is important that they can handle a heavy load. You do not want cheap plastic wheels to break and crack when you least expect it.
CONCLUSION
On the whole, my first choice would be the Barker 4-Wheeler Tote Tank - 42 Gallon Capacity. Pretty much any waste tank can be emptied in one trip, you can tow it behind a golf cart or ATV, and it’s built tough from high-impact plastic, steel and aluminum. I feel confident that this tank is going to last for years and make draining waste from my RV a tidy process that involves no strong odors or cleanup. Check this model out if you need a new portable RV tank, and I’m certain you’ll find it trustworthy and convenient, too.
