but it'll cost ya alot more than a couple gallons of pink antifreeze and an hour of your time. You can Google or Bing 'RV winterizing' and you'll find videos and links on how to do it. Some RV dealers have winterizing clinics in the fall that show you the steps.
My procedure: Drain the fresh water tank. Drain the black and grey water tanks. Make sure the water in the water heater has cooled off. Stand off to the side and open the pressure relief valve and take out the anode rod (if you have one) or drain plug. After the water heater drains flush out the water heater. I use one of these,
Water Heater Tank Rinser - Camco 11691 - Water Heaters - Camping World. Inspect the anode rod, replace it and hand tighten it until spring. Close the black and grey tank valves. Locate the low point drains and open them. Open the faucets one at a time, both hot and cold sides. I start furthest away from the low point drains and work toward them. Make sure you do the toilet too. Don't forget the W/D hookups and outside shower if your have them. Let as much water drain out as possible. Close all faucets and low point drains. Set the water heater bypass valves to 'bypass' or 'winterize' position. Now you have 3 options, blowing the lines out with compressed air, using pink RV antifreeze, or both. I do both air and antifreeze. If you blow out the lines be careful not to use too much air pressure, I do about 35 psi and use one of these,
Blow Out Hose - Intersource D16-252 - Winterizing - Camping World. I blow out the black tank flush too. Open the faucets one at a time, both hot and cold sides until you feel air coming out. Again, make sure you do the toilet, W/D hook ups and outside shower. You should have a hose hooked up to the on board water pump. Put the hose into the antifreeze bottle, open the valve on the hose, turn on the water pump and pump in the antifreeze using the same procedure starting furthest away from the pump until the pink stuff comes out both the hot and cold sides of the faucets. Save some antifreeze to pour down all the drains and let a couple inches sit in the toilet bowl.
