We finally found some Rv anti-freeze at a local auto parts store, so we went ahead and used it to winterize the motor home. We decided against just blowing out the lines, because if any water is left in the lines, you could have a problem. We figured we're not going anywhere before next month, so we might as well go ahead and get it done. It's now predicted to drop to 33 tonight, and we expect it to be a little colder here. It's been wicked cold here all day, even 60 degrees, because we've had a cold wind. It's going to be chilly at the garage sale! We sure never had to worry about winterizing when we lived in Florida, but maybe we should have.
I did a little more research and found some information on the Directv website. If you take your receivers out of your local area, you are out of the "spot beam" area and will not get the local (abc, cbs, nbc, and fox) channels. You'll still get the other cable channels.
If you live in your Rv, you need to get a waiver to be able to use your receiver in your rv and get all of the channels. It's some sort of law. In order to get the waiver, you have to fill out the form and send a copy of your rv registration. It will cost $14 extra per month. You will get both east and west coast feeds, unless you have a HD receiver, (we don't.) I'm not sure what you need to do if you just travel a few months, but I think you can just call and have it suspended.
In the end, we decided to go ahead and get it set up. We filled out the waiver and mailed it off today. It could take anywhere from 2-6 weeks to get it started. We'll be gone long enough, that we will want all the comforts of home :)
We got more stuff moved over to the storage shed and ready for the garage sale tomorrow. We're hoping it'll be a good sale, despite the cold weather.
