We use the Camco Rhino Portable Holding Tank. So far, it’s been pretty durable and easy to use. A few of the campgrounds we have stayed at, do not have sewer connection at the pad, but do have a central dump station. If that’s the case, this tank will save you a lot of heart ache and work! Because, if you don’t have one, each time your tank gets full, you’ll have to tear down and drag the trailer to the dump station. If you have one of these tanks, you fill it up and drag it to the dump station instead. A LOT less work.
It comes with everything you need. EXCEPT a fullness indicator. We purchased a small pop up indicator that screws into the tank’s garden hose connector. Only issue there, is once you screw that in, there’s no air vent. So, you’ll have to bleed the air off by loosening the pop up indicator. It empties well, fills easy and transports easy.
Comes in 4 sizes: 15, 21, 28 and 36 Gallon
