Back to the OP's question....
Tank Heaters typically keep the contents at 40-44° F (4-6°C
Your bigger concern will be your fresh water hose. If you plan on doing a LOT of winter camping, you can buy a heated fresh water hose, but you need to make sure that the spigot is well insulated or heated as well.
The simple fix is to disconnect your hose, have a ½ a tank of fresh water and use it in the morning to shower/whatever and re-hook your hose to the spigot when the temps are above freezing.
