It is not hard to winterize the water system.
Drain all water and empty all holding tanks. Drain the water heater and bypass the water heater. I do not know if your unit comes with a bypass kit or not. If you are using compressed air you don't have to bypass the water heater, but drain it first. Close all valves and faucets after draining them. Decide if you will use RV Antifreeze or air pressure. If using air pressure you will need to have a small compressor or a tank of compressed air. You will also need a blow out plug that screws into your city water connection. Attach Open one faucet and wait until the water is done being blown out. Open a second faucet then close the first faucet. Keep doing this until all faucets and the toilet have had the water blown out of the lines and fixtures. If using RV Antifreeze you will need some type of pump. A hand pump if your trailer did not come with a winterizing kit, which is a clear hose that attaches near your water pump. You put the end of that hose into your jug of RV antifreeze and then open and close the faucets. The water pump will pump the antifreeze through the system. With either method you will need to pour some antifreeze down the drains to fill the traps. There are several other threads about winterizing your camper.
