You will want to winterize the fresh water system either by blowing the lines out with compressed air or by using RV antifreeze. This includes all faucets, shower, outside shower, toilet and removing any in-line water filter and draining the hot water heater. Make sure to bypass the HW tank if using antifreeze. It’s not necessary to put antifreeze in the fresh water tank but you will want to drain it. Turn the fridge off and leave the doors open so you don’t trap any moisture inside which can create mold or mildew issues. Also, put antifreeze down the drains to protect the traps. Not sure how your area is for rodents but you may want to take some protective measures against mice. Remove all food items as a minimum.
