If your camper will be connected to city water, you won't need to sanitize. Hook up to the city water, flush the pink out, and just use the water in the camper normal. (for a week or so, I'd use bottled water to drink), after that your system should be sanitized because of the chemicals in the city water. The difference between city water and your own bleach water solution is the strength of the chlorine.
Now, if you are on a well, you'll want to use chlorine-water solution, but not needed if on city.
This is ABSOLUTELY WRONG WRONG WRONG. And not just wrong, but DANGEROUS.
A water system sitting with antifreeze in it (or with just water in it, for that matter) can harbor all kinds of mold and bacteria. These are NOT anything you want on your hands from washing, on your body from showering, and POSITIVELY not to drink.
I would use 1/2 cup bleach/15 gallons of water. Drain everything as best you can, fill the tank, run through all faucets. Drain the tank again. Partly fill the tank, pre-dilute the bleach in about a quart of water, add the bleach, finish filling the tank. Open all faucets until you smell the bleach coming out. Let this stand for about 12 hours. Then drain and flush again several times with clean water.
