Winterization Checklist

Winterization Checklist

Empty holding tanks – Put in RV antifreeze: The entire water system needs to be drained in order to prevent freezing. Two items are needed, a wrench or socket wrench and a gallon or two of RV antifreeze. Use ONLY RV antifreeze in your Scamp.

First, open all of the faucets, including any bathroom shower or sink faucets. On the water tank, under the rear seat, there is a pet cock valve in the front left corner. Turn it 90 degrees toward the center of trailer. This will open the valve and drain the tank. This should also drain the water out of the cold water lines, if your Scamp does not have a demand pump. Close the pet cock valve when the tank is completely drained.

Open the service access to the gas hot water heater. Take the wrench and remove the white drain plug from the lower left of side of the water heater tank. Water will drain out of the tank, and will also drain the hot water lines. Locate the water heater inlet shut off and turn it off. This will be accessed from inside the trailer. It is on the blue water line at the back of the water heater.

Pour RV antifreeze into the fresh water tank. Close all of the faucets. If the trailer has a hand pump, pump it until RV antifreeze comes out faucet. Pump the antifreeze down the drain until sink trap is full. If an automatic demand pump is used, turn the pump on. Open the cold water faucets only until antifreeze comes out, again filling sink trap. Repeat this process in the shower. Also fill the floor trap in the shower. Hot water lines should already be drained except between the pump and the tank.

RV plus

Pour RV antifreeze down the trap in the bathroom and turn on the pump that transfers grey water to the grey water tank.

Flush the toilet several times until RV antifreeze appears in the toilet.

Drain the grey and black water tanks completely.

Battery: To prevent the battery from discharging over the winter, disconnect the battery. If you are in a freezing climate, remove the battery from the trailer and store it indoors to prevent the battery from freezing. Do not store the battery directly on a concrete floor, as this will destroy the battery. If the battery is not disconnected or removed from trailer, make sure all twelve volt lights and appliances are turned off.

Propane: Make sure the propane is turned off at the tank. Also make sure all appliances are turned off.

Annually, and anytime any repairs or changes are made to the gas system where gas fittings are loosened, the system should be thoroughly checked for leaks.

Removing weight from axle: Leaving the weight of the trailer on the suspension for extended periods while stored is extremely hard on the torsion axle. The rubber suspension will compress and not relax as fully as before. Jack up the trailer at the frame and block it up to take the weight off of the suspension. The tires do not have to be off the ground. Relieve tire pressure to 10 or 15 pounds while stored. This will extend your tire life.

Locking down windows, etc: If the trailer will be stored outside, check all windows, service doors, roof vents, and entry doors to make sure they are properly closed. If the trailer is stored indoors in a secure place the windows and vents can be opened to air the trailer out.
