I know what my swimming pool would look like if I left it sitting there for this long.... As a precaution, I plan to take drinking water with us on our trips.
I do mine in the driveway. First of all it does not take a lot of bleach to do a sanitization. You probably use more bleach when you do your wash.
Algae does not grow in the dark. If your tank is covered you won't have that worry, but bacteria can and will grow in the dark. Chlorine will degrade with sunlight and evaporation and neither is a problem in a closed system like your RV. Once you have chlorinated water in your tank again, it should be no more dangerous than the water in your house pipes.
The problem comes when you drain it for winterization. Empty pipes and tanks are breeding grounds for bacteria and need to be sanitized before use. RV (non-toxic) antifreeze is great at keeping stuff from freezing but not so great at preventing bacteria growth. After dewinterizing you must sanitize to have a healthy fresh water system.
If you use well water in your fresh water system, there is obviously more chance for bacteria growth and I believe the suggestion is a monthly sanitization to keep it safe. (I would use bottled water for drinking in this case anyway).
As an aside, I carry distilled water for the Tassimo coffee maker as it triples the life of the internal filter.
