Welcome to the site. You have come to the right place for answers and we hope you share your experiences with us as well.
I have copied this question to the general discussion forum so you get more exposure to the question.
First of all, as far as using the city water versus your on board water, I use a filter on the outside of the rig where the hose connects to the rig. I use a 2 gallon per minute(GPM) one. It is used to reduce sediment, chlorine and bad taste. I have found that filters reducing the flow lower than 2GPM just makes the water flow too slow.
You should also be using a water regulator to protect your rig from excess water pressure from the campground. I use one that has the guage on it so I can see what kind of pressure I am getting. If the pressure is too low, I will switch to the onboard tank.
Now, as far as the on board tank, I do not leave water in it more than a couple of days before a camping weekend and drain it after I get home. I always add 3 tsp. of liquid bleach per 30 gallons of water to the tank when filling to add needed chlorine. If I am going to a full hookup campground, I still carry about half a tank in case it is needed. Then drain after I get home until the next time I go out. Your manual also tells you how to super clean it yearly.
