Portable RV Waste Tanks Come In Handy

There are several portable “dump” tanks available to RVers. Most are familiar with the blue tanks with wheels and they come in gray as well. These tanks will help extend your stay while dry camping without having to move your rig to the dump station. Simply hook it up to your sewer hose and empty your black or gray tank into it. Make sure you have one large enough for the job. You may need to make several trips. You don’t want to overfill and overflow one of these when the “fecal express” is connected. I like the type with a “T” valve so you can attach a sewer hose when you dump. The larger units have a handle easily attached to the back of a truck or golf cart and pulled to the dump station. A real convenient tool when you need one, but where do you store these tanks for travel? Some folks like to strap them to the ladder. Others load them on the roof if they have a storage rack. I’ve seen them tied to bumpers and strapped on the roofs of a tow cars. Helping you cart away your cares - Jim Twamley, Professor of RVing

Thanks Professor, I was wondering how people store these things. We have a short bed truck with a 5th wheel, and our bike rack is on the ladder. Not sure how we'd store one, but if we did, can you tell me;

How do you know when your tub is about to become full? When do you know to stop it before it overflows? And, as far as putting black water in there, isn't that kind of gross? How do you clean it out?

A great article. As for ourselves, we never stay long enough in one place to fill the black water tank. But grey water is a different story. We carry two tanks in our truck one for grey and one for fresh). A Tank Buddy pumps the water into the truck that is gravity drained at the dump site. Then we fill the fresh water tank and return to our sight. A 12v pump on board pumps the fresh water into the RV.
Each time we leave a site, that is when we go to a dump site and rinse the black water.
We can no longer lift things so this is how we handle the problem.

All is well unless you are "Really" boondocking many miles from a dump site! Those "tote tanks" won't tow over rough roads very far before coming apart. They are Ok for short distances.
We can stay out for 7-14 days w/o dumping or needing a tote by watching our usage. By that time it is time to go as a rule!

How do you empty one of these? Is it simply opening the tank and tipping it up and dumping it out? Or is there a more civilized way to do this?

I have one of the gray portable tanks. It's great for connecting to a hitch of your vehical but once you get to the dump station you may run into trouble if the dump station has concrete built up around the dump station hole to keep any black water from escaping. The rise around the dump station may be similar to a street curb and rises about 4 to 5 inches. It's a bear to lift your portable tank up over the curb and into the dump station square which is about 3 feet square. The portable tank must rest on it's belly on the curb in order to swing down the spout for dumping. The wheels are up in the air so it's not very stable. Once it's empty it can be handled with ease but when it's full it may weigh as much as 150 lbs.

We love to stay in the uncrowded spots away from it all.
Isn't that why we all started RVing. We found a great answer to the problem and it allows us to refill our freshwater also! It dumps up to 70 gal waste at a time and goes long distances with no heavy lifting or tote needed. I love it, it pays for itself IN CAMPGROUND FEE SAVINGS.
