Water tank & insulation
I don't think you need to insulate the water tank as much as you need to provide better access to internal cabin heat so as to prevent freezing when close to the freeze point. The Freedom Elite has a primitive heating system without out any ductwork and there is no way to easily vent heat into this area in an attempt to keep it warm, as a result you desperately need a fresh water tank heater option.
Happy camping and stay warm, because a frozen water system means you will need to replace your water pump. My rig had a previously frozen pump which I had to change out.
