Some coaches allow for connecting a water hose for both coach water and fresh water tank filling.
Others have a separate fill port for both where the fresh water fill is just an open gravity fill hose with a cover and the other is for a hose connection.
Either way, the easiest way to add a sanitizer is to pour the sanitizer into an empty hose, then connect it to the hose port and turn the water on.
Or, if flowing to a gravity fill hose, pour the sanitizer in the hose and screw some means to shut the water off on the end of the hose. Close the shut-off, turn the water on, pick up the hose and insert into the gravity fill port, then turn the water on.
I’m surprised they are recommending using vinegar to sanitize. Normally, sanitizing is done with straight everyday household bleach (not the scented kind).
Vinegar is usually used to help neutralize residual bleach odors after it’s use to sanitize,
