Probably the most important option is size. You can find a multiple of sizes but the most common are in the range of 22 and 35 gallons. Really the size you choose should be dependent on a few things, length of your trips and available space. If you have a particularly cramped RV, then perhaps you might want to forgo the 35-gallon tank and opt for something that won’t take up so much room. The same applies with how long you usually park someplace that the opportunity to empty the waste tanks isn’t readily available. If you like to stay put for a long period of time then a larger portable tank will work much better for your situation.

The are a bit bulkier but also have a self-storing hose that prevents it from being damaged or lost. Also a nice feature with these models are the outboard wheels so that you can simply roll it along the ground instead of risking dropping it and damaging it.
