Since it is now mid-September, and I do not know the answer because I just purchased a new RV in Jan 2014, I will start with the annual fall question:How do you winterize a Class "A" with a residential fridge with ice maker and washer/dryer?Also, Do you have to do anything special to the bathroom if you have procelin fixtures?Thanks,G George

I'm thinking out loud here, because this will be my first winter owning a Class A as well. Not sure about your fridge.Wash/wax exterior and deep clean interiorPotable antifreeze in the water tank and lines.Fresh, full tank of fuel with preservative (leaves no space for condensation to build in the tank)Run generator fuel line empty if you have a cut off. If not, then run enough to get the fuel with preservative in the fuel line and carb or injectors.Baby powder on slide rubber seals to prevent stickingLube all slide tracks/gears and pull in slides.Lube awning tracks and make sure awning material is dry before storingLube stabilizer jacks if recommended for your coachRemove all food(including dry goods and spices)Bug spray and rat bait everywhereDisconnect batteries and connect trickle charge if desired/availableWhat did I miss?

How long to you plan to let the coach sit unused? Will you have shore power available? Will it be parked on the dirt, grass, gravel, blacktop, or concrete?The rubber seal on your toilet can tend to dry out if it is left dry for an extended period of time. A coat of petroleum will usually keep the seal flexible.

This is what we do:Drain water heater, leave plug out.Drain all holding tanks and open low point drains.Blow out water lines with 45 psi air, opening each fixture one at a time until only air runs out. Don't forget outside shower and toilet lines.I leave all faucets open.Fill each p-trap and toilet with RV anti freeze.I do not use anti freeze in lines or holding tanks.

We just disconnected the line ( found behind the vent on the floor by the fridge). There is a T valve with a shut off on ours. The line comes from the cold water line from the sink area. I disconnected the line coming from the fridge and let the water run out and allowed red pop throughout the T valve, then shut it off never to be used by us. The washer will need to be cycled on hot only and then cold using the red pop as you do on the faucets . Let it get a little into the washer then run it on the drain setting to get it through the pump. I just pull the line off the water pump in the bay which goes to the water tank and add my syphon hose. A little advice - you don't want to be running back a forth changing one gallon jugs outside as they run dry. Dump them into a 5 gallon pale. I use about 4-5 gallons to get everything done good. What's left over dump down the traps. Takes about a 1/2 hour once you get the hang of it.

Point the rig south and start out.Carry a picture of a snow blower.When you find a hardware store that says:"What's that?" you are winterized.Sorry, I could not resist teasing a little.
