An RV dumping and fresh water filling station located somewhere in Florida.

Unless you stay at a Full Hook-Up campsite, anyone who uses an RV has to stop at a station like the one pictured below to empty their Black and Gray holding tanks and/or to fill up their Fresh Water holding tank.

If Shannon & Ray, Colin & Sheila, and Alison & David each owned motorhomes, they would be stopping at places like this either while they’re driving on the freeway or if they don’t stay at a Full Hook-Up campsite. That is, to empty their Black and Gray holding tanks and/or to fill up their Fresh Water holding tank.

The same applies to a Fifth-Wheel trailer.
