Pretty much the same as wmoses. Sanitize in the spring when we dewinterize. We rarely carry more water in the FW tank than to allow for a bathroom/handwashing break. If you know that you're TT is going to be sitting in the hot weather for a while, suggest you drain the FW tank....we didn't - as we usually do - and after a few weeks we started getting a funky odor. Finally tracked it down to the water left in the tank. Had to re-sanitize and we were good. We always camp with at least water/electric and when we can FHU. We use the hookup water for dishwashing and showers, but we installed a PUR faucet mount filter for drinking/cooking. We don't like the idea of a zillion empty plastic bottles in the landfills, so this works best for us.
