This is our first year with a motorhome and I I have a few questions about winter storage.1. Any recommendations on the fuel level to maintain over the winter months. We are in cold upstate NY.2. I was told to add an additive. Any recommendations on type? Do you add it once and that is all?3. I was planning on starting it at least once each month (unit is only 5 minutes from our house), is that satisfactory?4. Also assume would need to test generator monthly as well.Thank you in advance, i know about the winterization of the unit itself.Mike

You are a little early to think about winterizing.It's was 92 in Buffalo yesterday!

Could you please let us know the make and model and whether diesel or gas.

Add any stabilizer you want and fill the tank. The drive home from the gas station will get the stabilizer into the fuel system.As for starting it and running it, it normally does more harm than good. Unless you are taking it for a 20 minute drive all you are doing is running the battery down and inducing water/moisture into the exhaust system helping it to rust.Putting a battery tender on once a month to top off the batteries is not a bad idea.My opinion. Others will have their own. Good luck.

Keeping sun and rain off the roof, as much as possible, should be the first priority.If possible without too much work, a 30-60 minute drive every couple of months would be very good. It takes that long for engine oil to get hot enough to drive out any moisture that may have accumulated.

If there is water in the fuel, it most likely came with the fuel. Look up the numbers on how much water is in 20gal of air. Even if the air changes over once a day and you squeeze ever last molecule out, there will be just a few drops over the course of the winter.2) A fuel stabilizer is not a bad idea if it's gas. The ethanol causes gas to have a shelf life and this partially negates that.3) Unless you put it in gear and get it fully up to temperature, you are doing more harm than good. Assuming you are up north where they use salt on the roads...Better to put her to bed and take the battery home and put it on a battery tender (or charger every month or so).4) Same treatment for the generator. Unless you run it long enough and under enough load to get it fully up to temperature, more harm than good.

First of all, I am fortunate to have indoor storage available for our Roadtrek. For winter, here is what I do beyond winterizing.

1. Keep the gas tank full. Probably not necessary these days, but old dogs don't relearn their tricks.

2. Use a simple battery cutoff switch on coach and chassis batteries. Here is what I use:

You can buy them at Walmart or most places for under ten bucks. Make sure the batteries are fully charged before storage. In northern climes, some prefer to remove the batteries and store them inside a garage.

3. I drive my RT about sixty miles once a month for all the reasons others have mentioned. I fire up the generator and put it under a good load (the RT has a heat pump so I just set the thermostat sky high, crack the back windows and use that for a load.

4. I fill back up with gas before putting it back in storage.

I feel that it is imperative to run the generator for at least an hour and some manuals suggest two hours every month as a minimum.

5. Other than that, I protect it like I would any vehicle.
