It goes without saying (but I will), never drain your hot water tank through the camper's low point drains. The repair bill you save will be your own.

Good advice, especially for those of us that tackle our own maintenance/ winterizing etc. Cleaning out a plumbing system full of crud from the HWT because... you let it go there, is a PITA. Ask me how I know.
