Sanitizing ACE 30.1 fresh water system

We have a new 2016 Thor ACE 30.1 and I'd like to sanitize the fresh water system. All the sources say something like "mix one cup bleach with a gallon of water and pour into fresh water tank." That sounds straightforward enough, but I have (at least) two issues.

1. The filler for the fresh water tank is high up, presumably so water doesn't flow back out! I can get a funnel, but I'm not sure I can safely pour a gallon of bleach water above my head. I'm thinking it would be good to be able to attach the flexible filler I put on my potable water hose to a gallon container to pour it in. Does such a container exist?

2. That leaves the part of the system from the (separate, in fact on the other side of the rig) city water inlet to where the streams join untreated. If I had a container with a hose bib that I could put the flexible filler on, I could also put a short length of hose on it a run some sanitizing solution in through there.

Or is there a simple answer I'm missing? The simple answer we applied when in the past with an old old Santara Class C was to regard what came out of the tap as wash water only and carry many bottles of drinking water. I'd rather not continue that.

Have you thought about using one of these


Also read the sanitizing instructions. I believe it is 1/4 cup bleach to one gallon of water for every 15 gallons of tank capacity.

I empty the water hose, install a funnel into the hose, fill a 1/2 cup of bleach into the hose. Then hook on the filler tube and insert into the fill hole and turn on the water. I only fill just a little above the first indicator lite.

I have always used the winterizing hose off the water pump. I take a gallon jug 1/4 cup bleech fill with water, and let the system do the rest. Yes for the fresh water tank you have to go through the fill port. For that I have put filled the fresh water hose up with bleech then attached to water faucet filled fresh tank to about 1/3. This way the hose and tank are sanitized.

For both our Axis and our old 5th wheel: I would take a standard bottle of water (the kind you get in cases at the store), empty the bottle of water into the tank (no use wasting it) then using a pocket knife cut about a 2" hole in the side of the bottle. Then I use that bottle as the funnel to go into the water tank (for these two campers the top of the bottle fits pretty snugly against the water fill). Pour the bleach into the hole on the side of the bottle as you hold it against the camper.

Then I simply recycle the water bottle when done (don't have to worry about sanitizing a funnel at the same time).
