Yes just came across that on some issue I was looking at, for 40 gals 1 cup for 50 gals 1 and 1/4 cups let it set for 4 hrs or over night. You find that if you google it.

Even if you have full hookups, the chemicals put a significant strain on waste systems.
I understand your point, but I think rain water probably has more chemicals in it than the concentration of 1 in 800 bleach to water.

I run it to the fresh water holding with the tank full than run the pump to flush it through ALL faucets to kill the germs that may have built up

The forest river manual states 1/4 cup of bleach for each 15 gallons of water.

I know that anti freeze is poisonous to cats, so I wouldn't take a chance by not thoroughly flushing out the system before using water for drinking. Sanitizing at least once a year makes sense too.
The antifreeze used in RV is not the same as the antifreeze that is used in automobiles. RV antifreeze will not kill you. It does not have a good taste.

Auto antifreeze is ethylene glycol. RV antifreeze is propylene glycol.

I sanitize the fresh water tank, drink it to brush teeth, cook with it. Use bottles water for ice maker as most drinks are some other beverage. If the water is skunk like or high chlorine the water softener and filter usually look after that.
