Portable waste water tank recommendation?

For my peace of mind in case the grey or black water tanks fill before my departure I'm thinking of getting a portable tank. Any suggestion? 2 wheel? 4 wheel? I hear of handles breaking, wheels coming off, etc. 30 gallon tanks on TT: wouldn't 32 gal portable be better choice than 27 gal? Extra weight a problem to tow? Your ideas/experiences are appreciated!

I would recommend getting a 4 wheeled tank with air filled tires only !
I had one with plastic wheels and theyc broke the first time i tried to tow it behind my truck.
Also get a portable tank bigger than your waste tank. That way when you dump your holding
tank you will not have to be worried about overflowing the portability one.

I picked up a barker tote.
Wheels look cheap, handle cheaper..
I didn't care, because i can pump up into the bed of my truck with the macerator. The tote will ride there.

I have the 42 gallon Barker because I know it will handle our 30 gallon gray tank plus some extra water in the bathtub/pipes without overflowing. Empty I can pick it up with one hand. I store it in the bathtub while traveling & then chain it under the TT when we arrive. It has the better air filled tires & can be hitched to our TV for a ride to the dumpsite.

I also have a 48 gallon freshwater bladder that I fill on the return trip. I place it on top of our Ram's fiberglass cap & then gravity feed through our exterior filter into our 48 gallon FW tank. When not in use it folds into about 1 cu ft. space. This combo allows us to camp at state parks without taking military showers.

Barker 42 gallon, pneumatic tires, steel handle, wheel bearing grease fittings. Need I say more? Found one online for around $200.

Thanks guys! That Barker with pneumatic tires looks good.
I think I will pass on emptying the black water tank with the one gallon milk jugs!!

I have camped twice this summer for a week each time with electric only sites. The first time I used an 18 gallon 2 wheel tote from out tent camper days. it worked fine, but I had to tow it when I needed to dump. I found a 1st generation Thetford 4 wheel, 35 gallon tank on Craigslist for half price and picked that up for our second week at a state park. It, too, worked well and allowed me to pull it like a wagon (by hand) to the dump station. I even used it for the good stuff (black water) half way through the week as an experiment that thankfully worked out equally well.
In these adventures, I learned a couple of things. A 35 gallon tank is BIG! Travelling, I stored it in the back of our van, but it takes up a LOT of space and while it's not that heavy when empty, it is bulky and a bit awkward.
A 35 gallon tank is HEAVY when full, over 280 pounds. I could pull it fine on the road, but in the dirt near the rig, it was a handful. I am 6'2" and a smaller person might need to think carefully about how they will move a full tank. As one poster suggested, they use a macerator pump to fill the tank in the bed of their pickup, so that is one way. if you know in advance you will always tow the tank, a 2 wheel tank is lighter and less expensive, but you need to think in advance how you will move it to the back of your TV, just as with a 4 wheel tank.
Emptying the tank: The Barkers are attractive because they have that side valve for emptying. You do have to carry & attach a hose, Etc. and store it somewhere-doable, but you have to think about it. The Thetford has the integral hose and it worked well for my use. I did not have to think about carry anything while walking from the trailer to the dump station.
Wheels: Depends on the ground surface you'll be on. I like the solid tires on the Thetford and they worked well for me. The pneumatic tires on the Barker are attractive, it just depends on what you think will work for you.

Good Luck!

I use 42 gal Barker. Leave it in back of truck and use flojet pump to fill. Empty at dumping station with regular hose. You could use a cheaper tank doing it this way. I had Barker before macerator.
