So I can probably conclude that the well water itself is rusty, and the source of the smell isn't coming from my camper plumbing. The water heater is brand new, but both cold and hot smell, and the fresh water tank has never been used, nor is the water discolored, but my 3-week-old toilet bowl is showing signs of rust streaks already. My only hope is to use some type of rust-removing filter or water softener?
Easiest removal would be to use a Birm cartridge for a filter connected at the RV's hose connection. Birm cartridges are made from a specialty media product designed to remove iron and manganese. Removal percentage will depend on flow rate, slower flow meaning higher level of removal. The cartridge is capable of enough flow rate to use for the whole RV, although the total effectiveness will be reduced as flow reaches maximum capacity.
LinkTo remove rust stains from toilets, sinks, sidewalks, etc use a product called SuperIronOut available at Walmart, Menards and other places. It's a powder that when added to water that chemically converts the iron and makes it disappear without scrubbing.
